By the notorious 348 Brotherhood! LOL Back to the initial question. In a nutshell, the 348 has the best value for the cost right now - stay with a 1993-1995 model. The GTS and GTB's are harder to find in this range. Spiders a plentiful ('94 and '95). If you have a bit more moeny to spend and want a further refinement of the series, then a 1995 355 is for you. 1996's have different ECU's and slightly less HP. Moreover, the 1995's "hot rod" better. Check these boards for the 355 issues, but essentially watch for valve guides and exhaust manifolds. 348 issues are, um, not that many I guess for the later cars. Water pump, flywheel grease packing, those stupid motorized mouse seat belts.
