Excellent suggestion. Yes, quite naive of me to fall for a line like that. Lolif you decide to purchase check the frame inside and out for rust. They rust from the inside out.
Use a boroscope or long flexible magnet to check the inside of the frame.
Also aren't all dealer sales garage kept and owned by an old lady who only drove on sunny days??
Ive never used either of those instruments, but I’m going to bring a friend of mine who is a mechanic, maybe he will have one.
