Today I bought a 2008 Saturn Aura XR from my local Ford Dealer, Northgate Ford. It has the 3.6 liter DOHC V-6, according to the specs I found online it has 252 horsepower and 250 ft.-lb torque @3,000 rpm so it should be my fastest car yet, assuming its lighter than the Aurora. It is being inspected and prepped for me and a free OC before I pick it up next week. There is a small dent on the driver door. He offered to fix it, but rather than do so I was gonna use it to take a few hundred dollars off the final price. OR I could ask them to do the Wynn fuel system service FST for me. I could easily do this myself. I put a bottle of techron in the tank, clean the MAF sensor, clean the throttle body, replace the PCV valve, clean the IAC valve (if equipped), run half a can of either seafoam spray or liquid (possibly both, depending on the results), replace the air filter, and inflate the tires to the proper pressure. Once I start the car again after the seafoam soaks in, I head out for a spirited run in 2nd gear, 30-70 MPH about ten times. My real question is should I use the wiggle room that the dent gives me to have them throw in a Wynn FST, or do it myself and have them change the trans fluid and filter for free, possibly a full flush, and change the filter myself shortly afterwards? Or do all of it myself and have them fix the dent? I don't know if the Wynn FST is better than DIY methods because I've never had a car actually get to the point of actually needing it, since I usually do seafoam in the spring and the other items as needed.
