I agree with Tom. Body only really limits what a majority of modelers would be willing/capable of doing. I have started a couple resin kits that are trans kits, and even with the glass and parts supplied from donor kits, plenty of work is required to get it all together and looking presentable. Subject wise, I think I agree, all three are interesting. Right now, which would I buy - the LTD/Fairmont, then the Polara, and Jeep last. I would not, however, at this point in my life, buy a "body only" of any them unless they had donor kits available or, at the least, formed glass and interior.
