My sister bought one of those 1967 Corollas as her first car in the late 90's. Even thought it was 30 years old at the time she bought it, it looked like it was off the showroom floor. Still had the original tyres that she actually had to replace as they were crumbling, and there was no wear on the paint on the pedals. It only had 18,000 on the clock.
She was told by the car salesman that it was owned by an old lady who only used it to drive to church on Sunday (seriously, that is exactly what he said). We looked in the log book, found the ladies name and address and measured the distance to her local church. Multiplied the distance x 2 (got to drive there and back) x 52 (weeks a year) x 30 (years old), and the answer was 18,000.
First car salesman to ever tell the truth.
