i have a 65 and finding parts isnt horrible, if your looking to replace stock parts that are brokern. but finding anything aftermarket that fits is nearly impossible, such as bikini tops, diferent bumpers or anything like that. and check the wiring. mine is in stellar condition but im slowly finding the PO didnt know anything about wiring and half A$$d it so thats expensive, anyways,. the older the better inmo but the older the more love you have to put into it..
