Re reading my post I don't think I worded that too well... What I was thinking in my mind is that working out of a one car garage just flat out stinks. Even just 50 to 80 extra square feet can make a big difference. Based on the way you've described your garage, I think even though yours is larger, it doesn't sound like it lends itself to an easy working environement. A 16+ foot car in a 17' space can't be fun.
Personally I am more impressed with the guys doing nice work in tight quarters since it shows that it takes a little more ingenuity to get the job done. I'm very thankful to the guy that built my house for making the depth 25'. The width is sufficient if I didn't need to line the walls with cabinets, shelving, tool boxes, welders etc.... I'm fortunate enough to have some stuff stored in a shed, and some of the interior pieces are inside my house.
Back in the garage, I made a platform to set my compressor on the other day. It's about 10" off the floor, but I was able to tuck it up closer to the wall so it gives me about another 6" of floor space in a commonly traveled area. It helps a lot in that I'm not bumping into it all the time now. Little stuff like that goes a long way to making a one car garage a little more bearable for working on the car. We recently did some work to our kitchen, while the floor was open I ran copper pipe from the garage to the basement with the hope of moving the compressor to the basement freeing up some more space.
Currently I've got a few rafters that run the length of the garage with some leftover boards scattered about with all sorts of crap for my old El Camino stored up there. It's bigger stuff and only accessable by ladder, so I figured I'm going to build a loft with a floor so that I can move about safely to better organize for storage and possible as a light working area. There won't be more than 2 to 6 ft of head room, so we'll have to see how it plays out. I'm just trying to maximize what I have without it looking to cluttered or unsafe.
On the engine hoist, I managed to run 3 2x12s across the garage and hung a chainfall off of the beam. This is what I've been using for my roof and engine swaps, and it takes no floor space what so ever.
I hear you on the engines... one of the motivations for getting this Mustang was to get the 5.0 - T5 combo stuffed in the corner of the garage put to use.
Sometimes while in the garage I spend more time trying to figure out how I can better manage the space than actually working on the car. I find a tight / disorganized space makes it hard to get motivated.
