I am a car guy been a car guy for 50 years started on an old Ford F-100 pick up truck 1951,52. Through the years you learn a lot of things and pick up knowledge and tricks of the trade. Anyone can learn codes and Vin numbers because they’re In a “BOOK”. Anyone can learn to take a car apart and put back together, the only difference with this when you take it apart you put it back together with new parts. No matter what you do to the car it is only new once. And Mark all he knows is Numbers and how they go together which is all in the book and you don’t need talent for that. And Mark is not funny at all. The only talent I see on the show is the paint and body guy and the fabricator sorry Mark you have none.
