I really hope the administrators keep this post active. My post is intended to help some of you guys as much as I hope it helps me. I'm thinking about starting a repair shop for light duty trucks, with an emphasis on diesel powered vehicles. I thought what better place to do some market research than with guys who depend on their trucks to make a living. The basic question for me to answer is whether or not there's enough business out for the kind of shop I want. I live in a densely populated, near some very affluent areas. There's a significant amount of contractor work available and landscapers are kept going nearly 365 days out of the year. The shop would also specialize in doing diesel performance work. I specifically need to know if you guys have the time to do your own truck repairs, or would you pay to have mechanical and performance modifications done by a reputable shop. The guys I know depend on the dealer where they purchased the truck and that's not where they will always get the best work at the most reasonable price. The bottom line is that I don't see any good diesel shops around me. That tells me I either have a good idea or it's time to go back to the drawing board. What do you think? Have I missed anything? Do you have any advice for a wrencher that wants to strike out on his own? Thanks.
