Hello, just keep hearing/reading of avg weights of 3700 - 3900, yet my car shows 4423 at the door sticker, that seems a bit too much, please let me know if this is normal for an 05 A4 GTO, by the way I bought it from a dealer who said it was a "gm program car". It had 673 miles and pretty much complete except for the missing dashboard emblem. How can I find out what it was used for, any suggestions???
