As some of the illustrious former posters have mentioned, the name of your business will dictate the type of customers you attract.
To start with, my presumption would be that you're going to need the run of the mill (boring!!) servicing jobs to help develop a customer base and get the $$$ coming through the door. Once you've established your credentials throughout the area you can start to focus on just the performance stuff and move away from the boring stuff!
Without overdoing it, what about Riverina Service and Performance Centre?? Covers both bases.
Another tip, don't use your own name or family name as the face for the business. Reason being is when you start making a mill a year and want to offload the business, it's a lot easier to sell a non private named business.
Sorry, overkill on info but my two cents for what it's worth!!
