Don, I have a garage AND a shop. The garage is attached to the house and actually has three cars inside of it. The shop holds three pickup trucks and three cars, along with two lawn tractors, a 5x8 trailer, a full bathroom, two benches, two rollaways, loft storage, two 16' long x 5' deep x 6' high metal racks for parts storage (like the big orange ones at Home Depot, but smaller!), stereo system, alarm, and a refrigerator.
darn right I work on my stuff!
BUT, I don't paint and I don't do trannies or differentials! Front-wheel drive cars are the scourge of the Earth!
