I've heard that the Diplomat was actually pretty common as an export model...but I guess it just depends on where it was exported to. I remember seeing DeSotos show up in two different Aussie movies. One was a '59 in "Road Warrior" an the other was a '58 in, I kid you not, "The Cars that Eat People". They were actually Firesweeps though, not Diplomats.
I feel this way about most 90s luxury cars, especially from Japan. The features they had back then might have been exclusive to the luxury automotive segement, but now can be found in pretty much any car.
If you take an early to mid 90s Acura Legend, Infiniti Q45 or even the Lexuses, the only thing that's special about them is maybe the leather interiors, power seats, heated front seats, auto climate control (single zone mostly), and CD changers. Maybe the rides are cushier and a tad quiter when compared to new compacts now, but equipment wise they're nothing special.

I actually favor 1968 as the first year of the coke-bottle shaped Dodge Charger, but the Charger was much the same in 1969 plus the Boss 302 Mustang arrived in 1969, which is my favorite Mustang. I like the looks of the 1970 Camaro & Firebird better than the 1969 models, but I don't think they were faster.

Saw a Subaru Justy today, along with an early 90s Alfa Spider. Not long ago the question was asked what do big old ladies (as opposed to little old ladies) drive - I saw the answer today, a 97-99 S500 that looks like it came off the showroom floor last week.

A while back I read that Subaru was going to reintroduce a sub-compact in North America, but I haven't seen anything lately.
Maybe someone with more knowledge than me, or a better memory, can tell us what the '68s were required to have that the '67s didn't. I believe they lowered compressions in '68, but don't know why.
The Justy name lived on in other markets, but as rebadged tiny cars.

Either the Baur convertible or the full cabrio were grey market cars, never imported thru official channels. If anyone were to go thru the trouble they'd likely go for the 2002 but the full convertibles were extremely rare anywhere in the world. I've never seen one myself.

But, I think it was the catalytic converter that really did it... as you note, in '75...
I had a 302 V-8 in 1977 that was rated at 135 HP...

Just think that 12 years later (with EFI) that same 302 wasn't making much more!

I don't blame the catalyic converters for loss of performance. I think that the worst performance was the few years before they arrived. My family had a 1967 Chevy with a 283 V-8 and then a 1974 Chevy with the 400 V-8. The 1974 was terrible. It seemed much slower than the 1967 and did not start well in cold weather. That year the car would not start unless the seat belts were fastened.
I think there are actually two factors at play here, that tend to get intertwined. When it comes to mainstream cars, the catalytic converter was actually a bit of a Godsend. The cars were more driveable, easier to start, warmed up better, got better economy, and so on, than their '73-74 counterparts, which were choked down with a lot of rudimentary crap that really killed power and economy.
However, because of CAFE restrictions and such, most manufacturers ended up dropping the few high-performance engines that were left, because they would sink the fuel economy averages. For instance, in 1974, the Camaro still offered a 245 hp 350. For 1975, the top offering was a 155 hp 350.
Pontiac tended to reserve performance for their bigger engines, although they did still have a 200 hp 350. Top dog that year was a 290 hp 455, an engine that would have probably been a good 375+ in gross terms. For '75, top 350 was a 175 hp unit (and I wouldn't be surprised if that was the California/high-altitude P-code 4-bbl.) Top 455 that year was a severely-toned down 205 hp unit.
I think the auto makers could have continued with these high-output monsters, even with catalytic converters. But, with high insurance rates, expensive gasoline, and CAFE breathing down their necks, there just wasn't that much demand.
With more plebian, mainstream cars, performance seemed to improve from 1975-78, but then a second round of emissions standards started choking them down again.
If you think that 139 hp '77 302 was bad, be thankful you didn't buy a few years earlier. In 1975 it only had 122!
It very well could have been. The 400 was usually a dog of a motor...sort of a workhorse. Designed to move a lot of weight, but not necessarily very quickly. In 1975 it only had 150 hp, although there was a 180 hp version that was used in the full-sized wagons, and as an option on the midsized cars.
The '67 283 would've had 195 hp gross, which probably translates to around 130-140 net (the 200 hp 307 dropped to 130 when they released net figures). In theory, the '74 would have an advantage of using the 3-speed THM tranny (400 I'm guessing, in a big car), while the '67 would've just had a 2-speed Powerglide.
However, the '74 was probably held back by a tall 2.56:1 axle ratio. I dunno what axle a Powerglide would've used in '67, but I'd guess around a 3.00 or shorter. The 283 probably liked to rev more easily too, as it only had a 3.00" stroke, compared to 3.75" for the 400.
Then, there was weight. My old car book lists the base weight of a '67 Impala 4-door V-8 at around 3600 lb. For the '74, it's 4200!
It's amazing, isn't it, what a difference 7 years can make?
As for 0-60 times, I remember Consumer Reports testing a '68 Impala with the 307/Powerglide, and getting 0-60 in 14.5 seconds. I'd imagine a 67 with the 283 would be similar?
Popular Mechanics got a '76 Caprice Classic with a 400 to do 0-60 in 12.8 seconds. However, in '76, the 400 was back up to 175 hp. Or, probably more accurately, the 150 hp version was simply dropped and the old 180 hp version was choked to 175.
So, given those rough equivalents, I could easily see a '67 Impala 283 being quicker than a '74 with the 400, especially when you toss in the sputtering, stalling, and other drivability issues the '74 probably had.

We had a '73 Nova six new, and while it was a great value for what you got, that six was awful in the mornings. You just could not take off in it after a cold start. It'd stall two or three times. We also had a new '74 Impala 350 2-barrel. While it was not a fast car, and only once did we manage to get 14 mpg when we checked it on a trip, it did not have driveability issues at all compared to the '73 six. I have always heard over the years that catalytic converters and high energy ignition much-improved driveability in that period, as well as MPG, come that next '75 model year.
However, I tend to take everything he says with a grain of salt, as he's a Mopar man. :P
The track is about 1.5 miles long, and they had cars displayed for just about the whole thing, sometimes on both sides, except the down hill portion.
I'll try to set up a link to the pictures in the next day or so.
There was some great stuff.

I agree with everything said above. Catalytic converters are not the reason for lower performance. Performance improved after they arrived, but not because they arrived. Fuel injection, better ingition systems and overhead cams are the reason for improved performance. The 4-cylinder motors of today with catalytic converters more power than the six cylinder engines of the 1960s-1970s without them. More and more cars are using V-6 engines to get the power of V-8s. I recently read an article that said that Lincolns and Buicks are now using V-6 engines as standard with V-8s as an option.
I guess those smallblocks still might have the advantage of torque, though. Your typical 302/305/307/318 was usually good for around 245-260 ft-lb or so, while the average 350/351/360 was probably good for around 260-300 depending on setup.
But, with the advantage of more transmission gears, broader torque curves, better revving engines, and quicker axle ratios, I imagine all those advancements make up for the lack of torque, and then some.
As for Lincoln and Buick, they've pretty much eliminated V-8's altogether these days! I think the only Lincoln that still uses a V-8 is the Navigator...the cars are all V-6 I believe. And, believe it or not, Buick is mainly 4-cyl these days! The Verano and Regal are 4-cyl only, and a 4-cyl is standard in the LaCrosse.
That's still pretty impressive for the time, though. And being SOHC and fuel injected, it probably had a wider power range, and better performance than that 250 hp would let on. I googled the 77 6.9, and it looks like it was good for 0-60 in about 7.5 seconds, and one source said it had a top speed of 144 mph! Dunno if that's real, or just a calculation though?
By 1977, the Corvette was down to a pair of 350's with 180 or 210 hp. Pontiac got 200 hp out of their 400...but only in the Trans Am or Can Am. It was only 180 in regular cars. The Olds 403 offered 185 hp, with a 200 hp option on the Toronado. Ford's 460 was down to 197 in most cars, 208 in Lincolns.
I think Chrysler still had a 440 that put out around 240-250 hp...but only in police cars. In civilian cars it was more like 195-205. I've seen a test of a 1978 Dodge Monaco with the 440, from the Michigan State Police, I believe. 0-60 was 9.2 seconds, and top speed was 132 mph.
So for the time, that Benz 6.9 was probably about the best blend of performance and efficiency as there was at the time, for a car of that size. Of course, as you point out, it definitely came at a price! Compared to $40K, a Cadillac Seville was a bargain at rougly $13,500...and that was the most expensive Caddy at the time, unless you opted for the limo.
Like shifty mentions, maintenance nightmare - along the lines of the 600, it exemplified the German fetish of being complex for the sake of complexity. It's a wonderful car when everything is working right, but that wasn't always all the time. They aren't worth much money today relative to their status at the time, and many today are beyond reasonable salvation.

My guess is that it would probably perform better in that car than any powertrain option availabe for the Regal in '76. According to my old car book, Buick no longer offered a big block in the Century/Regal for '76, leaving a 165 Buick 350 as the top engine. But even the big 455 only had 205 hp that year. And swapping out it and the heavy THM400 transmission for the modern turbo-4 and 6-speed would save a lot of weight, I'm sure.
I'm kinda curious about the new Regal. I see them pop up occasionally at car sites, and it does seem like a lot of car for the money. Here's one with the turbo, sunroof, leather, etc, for around $29K. Seems reasonable to me.
The turbo is the only one to buy unless you are going overboard and getting the GS.
