All Things Porsche



  • Hello all. I need some help please. I just purchased a 99 911 and it is in good shape for a 99 with 93k on it. I had to have new tires done and a few minor things but over all the car is in VGC. I want to know if there is anything I can do to avoid the major repair that I saw mentioned in another forum where the engine gets destroyed. I can not remember what that repair was but it sounded pretty serious and I would not be happy if I had to replace a whole engine. Anyway,is there anything I can do to avoid that major event in a bad engine?

    The real reason I am looking for help is the dealer I purchased from (small exotic car dealer) told me that his wife dropped a soda on the floor and it blew out the DME (?) computer under the seat? I am drying out the water that is under the seat and I think the real reason is the drains under the trunk in front of the firewall were clogged and the water was runing in and down through the stearing column opening. I cleared drains and think I resolved the issue. I had to take the seat out and turn up the carpet to dry with a heater. AARGH)

    I found out that they had to replace the computer under the seat as well as the one in the back somewhere and the key fob chip (or the whole key fob) The car runs as the chip matches the new computer just fine however the key fob will not operate and open the power locks. Additionally, I am told by the dealer that I can not replace the key which runs the engine and the doors etc. I fear losing a key and having to replace all of the parts mentioned above. BTW.. the dealer bought the new computers and matching chip (key fob) from a used porsche parts place in Oklahoma. I have the VIN number from the Porshce (2000 911) that the computer and DME key chip, came from but the dealer can stil not program the key to open the doors.

    My concern is I want the key fob to open the doors and lock the car as well as get another working key with the chip. How can I do that? The dealer say there is no way to erase the codes in the replaced parts to reset to my car. They say I would need to replace those parts again and that seems crazy. They would be $1500. I do not want to replace what is working. I find it hard to believe that there is no master code to completely erase and reset the codes in the new (used replacement) computer under the seat and back of the car. Are there any suggestions as to where I might be able to go to to get this info and get this fixed? I live in IL and really want to get that key fob to work and get a replacement.

    I hope that explains my needs for any experts to advise. I really look forward to hearing from anyone.

    My email is if anyone has any info to share.

    Thank you in advance.

  • I am looking at buying a used 911 and wanted to get some advice on how much servicing is likely to cost and any gotchas associated with this model / year. The car has low miles (<40K) and appears to look like it is in really good condition. Interested primarily in driving locally and will probably put +/- 10K miles on it per year.

    Any advice would be appreciated?

    Great cars, but are you sure the seller can prove this 40K mile business?

    And if so, that's not a good thing, as Porsche do not like to sit there for years and years. Frozen calipers and galling of the cylinder walls (from accumulating moisture from non-use) are issues. So I would certainly have the engine tested using a Cylinder Leakdown Test (only that test, not a compression test) and also have the brake calipers checked.

    A Carrera of this vintage is a long-lived car as a rule and does not require lots of maintenance for the type of car it is.

    Presuming you got a very good to start with, I'd think about $1,500 a year in regular maintenance (exclusive of tires of course)---that is, a major service in the Spring and another in the Fall, should do it. Naturally, added to that might be the occasional repairs that come with a used car.

    But really the whole thing hinges on a very thorough pre-sale inspection, and a further careful investigation of this low mileage claim---which again, is not an asset to reliability, even if it might be to value.

    According to Edmunds, the appraisal value for a private party seller of a 1991 911 Cabriolet is approximately $8,000. has these 911's listed between $18,000 and $22,000. Why such a large discrepancy?

    Edmunds True Market Value is a great and accurate system for modern cars, but it doesn't understand older Porsche prices. Go with Autotrader on this one.

    I'm interested in buying a used Boxster or preferably a used 911. According to Edmunds, a 1991 Cabriolet 911 should sell for about $8,000 from a private seller BUT on all the 1991 911's range from $18 to $26, 000. Why the large discrepancy?

    Thank you! I just saw your answer.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 58,504
    If you buy a used Boxster, stay away from the first few years of manufacture, and if you can afford the S, it's a lot faster and more fun.

    Also, if you're buying a 1991/911, stay away from production dates prior to June '91.

    I just bought a 2007 Forest Green CPO base 911 with 16,000 miles on it and I am very happy indeed!
    I don't understand all the hype that one needs PASM with 19" wheels. I have 19"/Pirelli Zeros, no PASM and the suspension is less harsh than that of my 2007 328i with sport package.

    "If there is one thing Porsche isn't afraid of, it's providing an abundance of choice. There are 20 different 911 variations alone, while every Porsche can be had with hundreds of options. The 2012 Porsche Panamera adds to its own automotive horn o'plenty with a pair of new models, the fuel economy-oriented Panamera S Hybrid and the range-topping Turbo S."

  • Hello everyone. I would like to know how the Porsche 911 of the early-to-middle 1960s handled compared to the C2 Coevette of the same era. Any information and opinions would be welcome. Thanks very much.
