Stu I have a mate who has been in motorsport for over 20 years, between us we have virtually every tool needed to run a garage, he has built pukka Rally and Rallycross cars in his garage for years, he has a vast knowledge on things like Suspension geometry, Engine building virtually anything Motorsport related, he has already a good name and customer base, I'm more than able to carry out servicing and more menial jobs that would bring in a regular Income, we have spent hours talking, doing the maths... and we have both come to the same conclusion, that to set up a business would be suiside, thats with us not having to pay wages etc...
For you to go in blind, with only a basic knowledge of mechanics, no customer base, and have to pay wages... sorry mate thats insane
