Yes...for instance,if a 1 year old car is driven 12,000miles in a year...and the 2year old car is driven 4,000 a year then yes. As the 2year old car has only done 8,000miles total,compared to the 1 year old car which has driven 12,000miles total.
Just my two cents here... SHE could get in the car if she wanted to... BUT if HE let her get in the car, there is something wrong with him. BTW, this situation could be very dangerous, in many different ways.
