First of all, $500 plus for a tune-up on a 2002 Ford Explorer? Dropped my car off and key in their slot box after hours. On their little form, I filled out a brief description of what I wanted done with my car. I was assuming, wrong apparently, that I would get a call the next day for them to tell me that they received my car and key ok, and that I would then have the opportunity to give them more details of what I wanted performed. However, the only call I got was 2-3 days later, saying they performed the tune up and that it will cost $500 plus. If they would have called me before any work was performed, which I thought was standard in the car repair business, they would have been told that the car repair was top priority over the tune-up regarding my budget. Though he didn't fix the car because it wouldn't make the grinding sound that I was experiencing, the tune-up wiped out my budget to get it fixed. It took me a year to save up for the car fix, but I ended up with a $500 tune-up consisting of a oil/filter change, spark plugs/wire and checking the fluids. I didn't even get that little sticker that tells me when my next oil change is due. I've had this type of tune-up many times and it has never cost me that much, even at a dealer. Bottom line, I think he's honest, but the practice of not calling the customer before any work is done isn't right especially for a costly service.
