From 1971 to 1973 I worked part time for a used car dealer. Mostly I went to the auctions and to the dealers with the buyer and we bought cars to sell. Many times we had vinyl tops put on cars and also body side moldings. What ever the boss thought would help sell the car.
ps - one of things this dealer would do it roll back the odometers. I seen cars with 99,000 miles go to 29,000 over night. Lots of them were Chevelle's and Camaro's as they were popular cars to sell. We often got 5 cars and when one sold it paid for all 5. Seen that many a time, lots of money to be made in the used car business back then, no laws to stop you from doing a lot of things. We would hit the big car dealers in the Chicago and but 10 cars at a time for next to nothing.
