My suggestion is to try to get an older one (pre 1975). the Q.C. was better. I had a '72 and it was really solid. Check the rims. They tend to be rusty on the inside from water entering the flat tire beads. They are super easy to fully disassemble and reassemble. They are heavy, but ride so smoothly and balance nicely. I'd get a small (20" frame) for your height. (this size seems to be fairly common around here)
