The cost of manuals is crazy, but you really dont need them all. The wiring diagram book would be good, maintenance items, engine tune up. You can also purchase a few at a time.

As for the alignment problem, check the rubber bushing at the rear of the lower control arm because it may be damaged. It really is a shame theydidn't use any eccentric bolts for adjustments. The upper mounting holes can be elongated for adjustment.

This car is for crusing not racing, get a 940 Turbo if you want a high perf car, imho. To reduce understeer, use wider tires. There really aren't too many performance parts available for it.

The dash lights are removable from below. I haven't had to replace the heater and radio lights on my '96 965. I'm fixing the A/c and I have the dash apart right now, the passenger side air bag is out.

How many miles? Timing belt change every 70,000 miles or else!
