  • I would think any car going 400K would be an astronomically rare occurrence. Certainly it's not something you can count on but I hope you make it. Mostly it takes money to get there....but really I'm not sure it's a good idea to push a car that far. Structural safety concerns come into play and the cost per mile goes up exponentially as you approach the 250-275K mark. Cars are really not built or engineered to go that long.
  • My wife has a 2001 740il with the original battery. I am considering replacing it now on my schedule rather than when if fails. I know this car has some complicated, temperamental electronics. Are there any special precautions that need to be taken when performing this exchange? In other words, is it as simple as disconnecting the cables, taking out the old battery, putting in the new battery, and reconnecting the cables?
    Mr Shiftright do you have any thoughts?

    Thanks
  • I would definitely do some research before disconnecting the battery---one thing that comes to mind is the radio anti-theft, if you have such a feature. You'd have to know the radio code. I'm not sure how your clock, etc. react to all this.

    So yeah, call the dealer's service department or drop in there and ask, or any competent independent shop would know. I don't think it's any big deal. I know some shops have a little "helper" battery device that keeps a small current flow into the cables as they remove them.

    Good idea to swap out the battery. Five years is long enough.
  • What is an Indy shop that you keep referring to? Also what should an oil change cost for a 740i. An Express Lube type place quoted me $100. which seems high. Should I get my filter and oil myself to save some $$$?
  • I recently purchase 2 740i sport 2001 cars from e-bay motors by auction with no reserve. The first went smoothly, but the second was a nightmare. I got a great price but had the seller try everything to make up for his losses; try to get out of the sale, switch the tires, take out the spare, missing phone, not as described both physically and odometer reading much higher on delivery, etc. Am I being too hasty in giving him a negative feedback, or should I have expected as much...?
  • Recently purchased the car and need the best service manual available. Is there a factory service manual available?
  • I am contemplating purchasing a 2006 750Li. Do the 19" wheels make sense as a $1,300 option? Visually, they look better than the standard wheel but will they make the ride rougher? Are they worse in snow? Thanks in advance for your advice...
  • my two cents, don't do it. Rougher ride, slower braking, more risk to the wheels from potholes, probably very pricey tire replacements. Not worth the nicer looks IMO, but aesthetics are personal, so buy what you like please!

    Heck yeah, they're worth the extra money. The standard wheels are ugly as all heck, IMO! The 19's look good, IMO.

  • Thanks for the responses, everyone. Any opinions on how the 19" wheels handle the snow vs the standard 18" wheels? "Mr Shiftright" says the ride is rougher and that's a turn-off for me. But how about handling in winter weather? Thanks again...
  • You know it'd be great if you could drive a car with these wheels on---because tolerance for "hard ride" is so subjective.

    I don't imagine that size has much to do with snow traction, but rather the tread designs available for the tires regardless of size...

    Actually looking just at the photos, I can't say that I see any dramatic difference. This is a BIG car, so the wheel size is sort of lost in the overall mass of the vehicle, to my eyes anyway.

    Maybe it's the fact that I've seen both wheels on 750's in person... Perhaps the pictures don't do it justice? In any event, there was a marked difference in the two. The 19" style is just so much more "luxurious" or something...
  • Well sure nothing like "the real thing". The photos don't seem to show a whole lotta difference.

    I've been cruising various forums outside Edmunds about this and one Benz owner said he went to 19" and his ride quality was not dramatically different---a bit firmer but he liked the firmer ride he said. Also he made a GOOD suggestion---that if you upgrade to 19"s, make sure the wheel is of the highest quality, as the slimmer tire does make the wheel more susceptible to road shock. So no cheapo discount wheels. Looks like yours are from BMW so that's good (I think!).

    Honestly, the ride is fine, the BMW rides much better than my 2004 E55 with 18 inch wheels.

    To me, the 19 inch is just about right, the car looks so much nicer with these wheels. The 20 may be pushing it but I have seen 21 inch wheels on the 7!

    You may want to check with BMW or tirerack to see if they make 19 inch winter tires? I think I may go with 18 if I need to put snow tires on, or 19 for summer and 18 for winter if I do not have a winter vehicle.

    The 750Li is a fine car, ask away if you have any questions!

    During highway passing and the engine drops from 5th to third, a couple of times it has felt like the transmission is slipping. Revs are high, but the car is not accelerating fast until it shifts to fourth and then takes off. Has anyone experienced this? Is this an adjustment that is needed or a sign that the transmission is going bad?

    How many miles do you have on the car?
  • mimeomimeo Posts: 10
    70,000 miles I have had the car since 35k mi. and have not previously had any trans problems

    In Addition, it does not appear to happen in normal acceleration but rather on-ramps or traffic areas when I am going relatively slow and need it to drop to 3rd to get into traffic.
