If she wants to drive it make her earn that up twocents
Also make sure that she has the needed training and skills to do that, I have disconnected the rear barrels on several drag cars for kids and new owners to learn how to get some seat time without scaring them bad enough to not want to go faster than 12.0 in the 1/4 mile to start with work
Is there room for her to do a ride along at the track to show her what your car will do? If so do that and make sure the car doesn't go faster than the track allows it to go with a passenger, if not start her off in something slower twocents
