308/328 are one and the same to pretty much anyone other than fibreglass car-seekers. (And sadly I don't own my 328 anymore, so I can comment without bias ...) A collector would likely want a '76 Euro 308 and an '89 328. I'm not a fan of the ABS 328s, but the market values those ~$5K more than the prettier earlier 328s, so it is what is. The best ones sell for more than sticker. (RM Auctions sold a time capsule 328 GTS for $90K+ this year.) Newman just sold his restored but not concours-accurate '79 308 in yellow for $73K. I can't imagine the buyer wanted it as a cheap daily driver. Not only are decent 308/328s affordable, but they are the last of the old school production Ferraris, the last Ferraris without expensive problems, and the last that were iconic. As long as the Ferrari badge has cachet, really good original 308/328s will be in demand. The exception may be the "middle cars", the GTBi/GTSi. On the VW: Yes, the Corrado VR6 is rare, but mine had valve lifter issues before 10,000 miles and had the worst torque oversteer I've ever experienced. Plus motorized mouse seat belts. Plus rubbish first-gen Teves ABS, probably the same tinkertoy technology Ferrari threw on the last 328s. Moreover, the big hp advantage it had back then (178 bhp in 1992) doesn't put it midpack anymore -- the 2.0T Audi TT spanks it and is better in any way I can think of. The Corrado was a big deal at the time, but now it is old, expensive to fix, not all that fast, and too plastic to be classic. On the E36, I'm no expert, so the lightweight rarity may be much harder to find. But, is it distinctive enough that people will pay a premium for it? There are scarce cars, like the Triumph TR8, BMW Z3 coupe, etc., that weren't bad, but appeal only to the lunatic fringe of marque devotees and so don't appreciate much in value. As someone else suggested, there are the irreplaceable cars of the 1950s, '60s and '70s, and then decades of mostly junk brightened only by major league stuff like the Ferrari Boxer/308/328, McLaren F1, Lambo Diablo, etc. Anything else we should all be able to write a check for anytime in the next 10-20 years before they're all recycled into something better. If you want an affordable collector car, the '69-'73 Porsche 911T is a deal, can be rebuilt to smoke a lot of '80s and '90s sport-econo cars, and won't lose value. The 911S's of that era are already pushing $125K. I wouldn't bother with most of the recent cars, other than the 308/328 -- and I'd be picky with those. I also like the Lotus Esprit, just because they are so much car for so little cash -- I can't imagine them getting any cheaper.
