Not to start anything with Zen, but an hour and a half sounds a little optimistic on snap-together flooring. I installed RaceDeck in my 576 sq ft garage and it took me about 8-10 hours. Maybe someone younger and more experienced could shave a few hours off the task. I had to trim all the side squares using a table saw because I wanted a wall-to-wall fit. There is no way you can do that in an hour and a half. If you contact RaceDeck directly and mention that you're a VCA member, you ought to be able to get flooring for somewhere between $2.75-3.00 per sq ft.
I concur.... I got the 18" X 18" from Race Deck, yellow and alloy were the colors (My viper is yellow) they were a pleasure to work with, Shauna was the person that helped me. I got the VCA discount, and a little more. I have an extra large two-car garage, it took me 6-7 hours to complete. The cutting takes the most time, its perfect though, and its an easy install.
I would put down a barrier (tar paper) over the concrete to eliminate the hollow sound when walking on it. Yes, I would do it again.
I also went with the Gladiator garage system, cabinets, shelving, etc. on all walls (VCA discount applies as well) and everyone who looks at my garage says its the nicest garage they have ever seen, of course it does have a Viper in it as well, which helps. I did this as well with my 16-year old kid. I only wish I had a six car garage.
For the Race Deck floors and the Gladiator system, a company estimated my job at @ $10K for everything, and I did it for $3K less, and still have $2K in tools left over from the job to boot.
Either way, good luck with the garage.
