IMO, that garage looks like its about 3x the square footage of yours. The main issue in your garage will be the space it eats up. Will you be able to use the other side if the lift is installed in your garage?
I'm in the middle of doing my M66 swap at my friends and he has the Snap On version of this lift in his garage. The major downside to the scissor style lifts is that you obviously don't have good, clear access to the middle of the car, like if you had to pull the drive shaft or exhaust or something like that. But its nice for what we're doing now, and I could see it being good for suspension and brake work too. In his garage w/ 8 1/2' ceilings it gets the car 3' in the air, and at that point the hood is on the ceiling.
