Motor Trend says 13.7 in 1/4. I just got my 03 L 2 weeks ago. It is faster than my modded 01 GT w/out the spray. When I do spray the GT the L is almost as fast. The GT ran 13.3 on spray. It has three seatbelts btw. In my opinion the ride and handling is better in the L also. I really like driving it. Ive only driven the stang once since i bought it... The L is also very temperature and humidty sensative, as is any blown vehicle. So you will be faster on a cold, dry day than on a hot humid day.
