Cheap "collectible?" Gassaver vehicles

[BumblingB]

This was a reply of another thread, but I figure it has the possibility of a complete hijack as it is worthy of its own thread.

I keep thinking more and more of antique microcars/subcompacts or even something such as the Beat.

Pros:
Great mileage
Super attention getter
Little if no depreciation

Cons:
Getting parts for some models
Getting PROPER insurance


I could go on and on with the pros and cons, but IMO, if you had the money and automotive knowledge (just in case it were to break down) I'd like search for something like that. I remember seeing a restored B210 for something like $6kUSD - a great price for something that gets decent mileage, is considered an antique, reliable, retro etc.

Anyone got ideas of a car that can be found for..........lets say under $12kUSD - US legal - over 30MPG - stylish (ones own opinion I guess). Let the ideas flow.....I won't limit this to cars as there are things like the old Crosley trucks that are neat IMO.
