I am looking at a 1999 996 with 72,000 miles.

Has had a lot of work done (RMS, clutch, etc) I can list most of the work if it would help you help me... :)

But the oddest thing is that 12,000 miles ago it had the transmission replaced.

It was replaced with a GT3 transmission that had 24,000 miles on it.

The explanation is that it had a 2nd synchronizing gear failure and porsche was not selling parts to repair the transmission, only new trannys.

The owner decided to look for a used transmission instead and found that one.

Should this be a show stopper or not a concern?

Thanks!

TC

This sounds like the kind of thing I would do, so I wouldn't shy away from that at all. If the factory transmission doesn't even hold up for 100k miles, why have it fixed or replace it with one exactly like it? It would be very expensive and is obviously not that strong (or maybe it had a previous owner that couldn't drive a stick very well). I would also spend a few more $$ and upgrade like this owner did.

I'm at around 55k right now. Don't have any issues with the tranny at all, but I have had head seals replaced at around 38k miles, the clutch, RMS and IMS replaced at 45k, and the RMS was replaced twice before that by a previous owner. The third RMS change wasn't actually necessary. I just ordered the parts because I was having the clutch replaced anyway and wasn't sure if the RMS was the revised version (or installed with the revised tool, I don't remember what was revised). The dealer said the existing RMS actually wasn't bad, just sweating a little bit of oil that probably wouldn't even show up on the ground.

There are other common repairs that shouldn't concern you - window regulators, coolant tank, radio, seat belt parts, etc.

I'm curious if the rear struts have been changed on that car yet. At 55k miles, my left rear sags AND feels fishy, like a bad strut, and I've read (though I cannot speak for the accuracy of the sources) that the one-sided sagging is not uncommon. Measure the rear fender heights on each side to get a rough idea.
