People in your area may be different but in my town, they will not share information like that. I have a high school friend that has been in the automotive industry for several years in the parts department. I tried to buy him lunch to pick his brain and I was told he would tell me parts distributors if I did his lawn work.
In his defense, people in the area are different ( to put it nicely). Therefore the research will be entirely on my own. This site is amazing for my situation.
I guess I really need to know who sells the bulk oil, the wholesale tires and so on. This will allow me to come up with prices and a plan to execute. I have been in the automotive hobby for over 10 years. I have repaired everything on a vehicle at least once. I have experience rebuilding engines, transmissions, axle assembly's and so on. I am currently enrolled in school and have plans to cut back half of my customers with my current business starting in January to peruse the automotive field. It will take time to be the one stop shop I have visioned. Therefor I plan to do brakes, wheels, suspension,tune ups, and oil changes to build clientele and equipment to offer other services.
