Just a quick tip on saving cash at the stealership. Find out everything that needs to be done, and go on the internet and buy the parts yourself. Then take the car in and have them use your parts. Wiper blades, air filter, spark plugs, serpentine belt, stuff like that is going to be a lot cheaper on the internet than through the dealer.
I stupidly had the dealer do a spark plug change, and they charged me $140 just for spark plugs, because they claim they installed Porsche Gold plugs, which don't even exist. Then another $200 for the install. I should have done it myself!
