He showed up to a new-years hangover run a few years ago in his 1000 hp twin turbo toronado. Doing burn-outs, having fun, he's a real car nut and a regular guy. He's just doing what we would be doing if we had the money. He drove that thing like he stole it.
I saw him at the festival of speed at cal speedway several years ago standing next to his tank-engine powered hot-rod. You have no idea how big that thing it until you see it in person. It is giant. He told he he got 1/2 mile to the gallon in it, but that was before he had Gale Banks install a twin turbo system on it. Something like 2500 ft. lbs. of torque and 1600 hp now.
He actually wrenches on his cars too. He has a full time staff but dives in and gets his hands dirty when he gets the chance. Working for him in his garage would be a dream job for me.
He's not a big Porsche fan tho. He has a carrera GT but
AFAIK that's the only Porsche he owns.
