My $02 (get it?) --
Go roundie. I agree with the; you'll be putting money into it, and it's no more expensive to resto an earlier car than a later car and I (and the market) prefer the earlier cars. You may spend what the car is worth to resto an older car (though you have considerable mechanic-fu and might not need to pay others much) but you're likely to wind up underwater with a later one.
ATEOTD, If I could keep only one car, it would be the '02. No question.
