Thanks alot for all the info! I'm still in the planning stages so I don't have alot of the details worked out yet, but the county I'm thinking of locating the business in is an upper middle class/wealthy area. Many customers will have excellent credit ratings, but I know that some of the wealthiest also have the worst. I hope to carry mostly higher end luxury imports and cater to the business man, soccer mom, and the up-and-coming teenage drivers who convince their parents to buy them a fancy first car (there's alot of them in that area).

I'll defiantely check out all of those links, thanks alot for that. I'm also reconsidering the full-blown quick lube place because as pete said, that would double the size of the business and make it that much harder to run, especially for a new-commer to the area. I was hoping to do my own warrantee work, service and repairs for the cars I sold as well, as it would eliminate the cost of having another mechanic do that work, but maybe that would be something I could add later on, as the business grows.

Thanks again for the info, this is going to be a long research phase (couple of years probably) but I hope that all the planning will help me succeed if and when I follow through with it all.
