Regret is a state of mind that is easily remedied. I had my car for the summer before AP hardware was added in Sept 2014. It was a great summer with my car, wife and kids (not necessarily in that order). The number of summers I have left in my life (and days) are winding down fast. I'm only 50 but still that leaves me with about maybe 25 good and healthy, being able to drive, summers left (knock wood). I hope it's 35 more. But the point is, even one day on this earth without my car is too long for me. While I have tinges of regret sometimes, I will never get that summer back with my car and it was a great one, and I wouldn't do anything differently.
