If you're tall then you will definitely want the lowered set base (if recaro), it makes a world of difference. These cars are getting on a bit and some will require parts, but IMO once you do the car will last quite a while and be very enjoyable!
My experience my be a little different to some others but I have found the car quite reliable and not super expensive to fix but that may be because I like to do most work myself.
Two biggest things for these cars (any 197 or 200):
1. Timing belt change. If this hasn't been done within 4-5 years or 100K kms then budget 1000-1200 for replacement.
2. Gearbox crunching. Check all the gears go in and don't crunch. If it does then synchros most likely need replacing and it is expensive 2.5-3K job (with new clutch).
Secondary things to look for:
- Front strut tops flog out. No way to see if they are damaged without taking the cowl off unfortunately. Listen for clunking from the front.
- Inner tie rods. Listen for clunking while turning, especially noticeable at low speed.
- Lower ball joints. Similar symptoms to the strut tops.
- Engine mounts (mostly lower dogbone and torque mount). The lower dogbone mount flogs out quick on these and if left will eventually split the exhaust manifold flexi joints. Torque mount can flog out and cause clunking under acceleration.
Like others have said, they are very fun cars to drive which can give much more expensive cars a run for their money in the twisty stuff.
