One thing to keep in mind is that ANY dealership makes a bulk of their money in parts, service and leasing. The actual money made when a new car is purchased is minor when compared to what they make on the three things I just mentioned. So if your car is still under warranty, that doesn't matter to you or them because the manufacturer foots the bill.
But when there is no warranty, WATCH OUT!
A good example is when I went to a dealer to retrieve my radio code. Before he looked it up, he said there would be a $25.00 fee for the TEN SECONDS it would take to look up on the computer. I had already taken the serial number of the radio myself.
I said they were crazy and I would rather replace the radio then give them $25.00 for a code on a 1998 cassette AM/FM. ..As I got into my car in the lot, he gave me a piece of paper with code on it. Very nice of him. It's obvious that the dealership will rip you off every way they can. They may give "NICE" service with free coffee and donuts, but you're paying thropugh the nose.
It's noone's fault specifically, just the nature of the business.
I've been fortunate as I have had no major problems with the car. I try to do everything myself, oil changes, tuneups, brakes, etc.
But if the car ever needed a major repair that I could not handle, I would go to a local mechanic who I have used in the past with other cars.
You have to find someone you trust.
