Should I buy an old top tank general with no gas cap, no mirror, no speedo, no taillight, and no headlight, with bad brakes and a little rust and a broken chain with a decent running engine. It is my friends and I drove it. It was pretty good until the chain broke. It is minarelli. I should be able to get it for $80 bucks or less, is it worth it? OR I could buy a decent running motobeacane that i think has just about everything but I don't know how much.
