Could folks here please post the weak points of the 993? Anything that is unusually prone to failure or otherwise is troublesome? I have been scanning the thread titles but no clear trends have emerged (which is itself a good sign, I think). I am contemplating a model change... trying to decide which model Porsche would best suit. Thanks in advance...

Steering rack,valve guides,wiring harness,window switch, depends on mileage and use.
Much better than 928s

I can attest first hand. I sold my '81 928 in SEP '04 and bought a '95 993. I loved the 928 but don't miss it a bit...... I felt is was a ticking time bomb..... Hmmmmm, let's see.... What is it this week? Timing belt, torque tube, electrical gremlin?
Thad,
I would recommend a '95 because it doesn't have OBD-II or Drive-Bloc. It suffers a 10HP disadvantage to the 96-98 and doesn't have varioram. However, dyno results put the two on par.
I'd be glad to talk with you regarding my experience. PM me and I'll give you a ring this week.

I agree, that Word.doc sums up the most common problems. Wiring harness (factory recall) only thing he really left out.
From my experience, 993s have relatively soft windshields (pitting/cracking quite easily), front bumper loves stone chips (like most Pcars), rear suspension a little sensitive to alignment (must have alignment done at a shop that knows how to align the "weissach axle" which you should be familiar with if you drive a 928), and rear tires last under 10k miles. Stock stereo very weak, and stock exhaust is very quiet.
Anyway, there aren't many *big* problems to look out for with these cars, they're very well built. A little soft and cushy for my taste, but overall no real problems!

Thad -
You will not be disappointed with a good 993. Look for one that has suspension and exhaust already upgraded, and 18" wheels from the 17" stock one (if you so like). Also, if the valve guides have been worked on, you'll be in good shape and miss a $6,000 to $8,000 repair. Good luck with your search.

2 people mention valve guides. Mine's got 62K and only uses 1 Qt oil every 3K mi. Does that mean a PO had the valve guides worked on? I only have the stamps in the book from the 1st owner, no receipts for repairs done prior to 20K miles. 2nd owner, the one I bought from, didn't have them done.
TIA

For the past 17K since the rebuild I have been running an unbelievable 1 qt/6K miles.
