Humm,
I don't think he tinkers with his cars because they are broke but because he doesn't want to put them on the track. Of course there was that one issue with the broken axel, and then the time when the back part of his GT 40 came off because he forgot to latch it down, and of course there was the time when he was chauffering a young fan around and found his way on top of some tires waiving at the rest of us as we went around the track. Oh and did I forget to mention the time he was at Road America and didn't quite get his knock off wheels completely seated on the hubs. We were going a thousand miles an hour when he came in and mentioned he felt a slight vibration! Just in the nick of time...so to speak!
Guys dont' worry about bringing a knife to a gun fight...he usually forgets his bullets too and did you notice he is running some old Chevy engine LS7 or LS9?
All kidding aside, Dean is a great driver and always has a very beautiful and capable car. We will put him in the class with all the hot shots with Supercars and big ego's. The rest of us will be in our ole Cobra's having much more fun for a lot less money.
