F-body owners and 10yr olds.   :no:   
Outside my first car, the ones we have now are the oldest we've ever had and at 4yrs/5yrs the ones we've kept the longest.   I hate getting to the point where we put routine maint. money in them.  Ironically today we just put $500 in the Van in new Brakes, rotation, balance, alignment, LOF and a strong cleaning.  Cheaper than a new car and beats having a payment.   
Congrats on the car!  It's no doubt been a fun time.
