Nice looking car too!
My wife and I were married in 2005 and similarly, we both wanted to get a new car as a gift to each other. (difference being we were both as excited with the '05 Mustang's new redesigned look) but we were also buying a house together which we decided was more important. We held off on the car at first, mostly because they said to leave your bank accounts (savings) alone during the process of closing the house. It was a good move to wait. We ended up adopting (buying used) our 2005 GT convertible in 2008 with 12K miles, a real bargain price and in perfect condition. We couldn't have been happier and still are. My only regret in buying the '05? It placed my restoration of my '67 onto the back burner and that was a bummer. The payments only lasted so long and the '67 is back on the front burner again, right alongiside the new roof on the garage they both are stored in!
Congrats! May you still have your '15 in as nice of condition at your 60th in '30!
