In the primer section you will find details of a PPI. Make sure your mechanic is well versed with the 348.
Pay specific attention to the gearbox and the Cambelts. These are the 2 achilles of the 348 mechanical systems. Look for Gearbox issue's with ring nut backing off. Real important. If the ring nut backs off to far, its gearbox time. The cambelt is critical in the 348 as the valves are interference fit. Failure of the belt or tennsioner can cause an engine scatter. Both of these potential problems are super pricey but rare.
Lots of junior problems with electronics usually caused by poor connections. If you buy, you will be dealing with each of them over time.
The 1990 model was half twin clutch plate and half single clutch plate designs. Both designs contain expensive parts so look for wear. It also used the motronic 2.5 fuel controls later switched to the 2.7 for many reasons. both are durable but the 2.7 is a bit more sophisicated.
Provided you are fairly mechanical minded and there is nothing huge going on you'll find the 348 awesome. The only task I won't take on is a Major engine out service. Beyond that, fun car to own. Its the last of the true sports cars made by Ferrari (no power steering, onboard suspension adjustment, power brakes, etc... You can actually feel the road)
