That's funny you should mention that. We just did the same thing. I bought a 1990 DL ('90s on have a driver airbag) with power windows and third seat for $2500. There's no rust on the car as the newer ones are galvanized (you won't find a galvanized turbo I believe, though in CA it doesn't rightly matter does it
).
The turbos are definitely quicker, more rare and thus have a better resale value. The non turbos have less to break and are newer. One may deduce for that reason that they are more reliable. For me, it was a matter of finding a car that was believably reliable. Our car, while it has 190K miles on it, was a two-owner car that the second owner put all the miles since 50K on in the span of 4 years. It was dealer maintained and mostly highway mileage. While the body isn't in fantastic shape, I believe it'll be a reliable car and that's of utmost importance to me. That said, there are guys who know a TON more about the 240s than I do, so I'll bow out to their greater knowledge.
