I noticed the other day that, from the back, the driver's side of my '08 GT convertible looked lower than that the passenger side. I was bringing the car in for service anyway so I asked the dealer to check it out. He measured and found that the driver's side was, in fact, about 1/2 inch lower than the passenger side. After congratulating me for my eagle eyes, he told me that this difference was normal and within spec. Is that true? Also, wouldn't it be a relatively simple adjustment to fix? If it were balanced out perfectly would I notice any difference?
