Mine wieghts in at 3448 without driver it is a factory lightwieght car. Hardtop with No power seats, locks,or windows.
I'd imagine a fully optioned car that with seats 75 lbs,windows and locks 100 lbs,t-tops another 50-75 lbs,optional stereo 25 lbs.You could end up with one that wieghts around 3700 to 3800 without driver.
