I actually had this same dilemma back in 2001, although I was newly married. I received an inheritance and we seriously considered if we should use it as a down payment on a house or buy a Camaro. Keep in mind this was at the time when they'd already announced the Camaro was being discontinued, so it was a now or never type deal. Well we ended up doing the "responsible" thing and got the house, saw it double in value, and fall back to reality. If we had gotten the Camaro, we probably would have had to wait a couple of years to buy a house, during which prices sky-rocketed. My reward for doing the responsible thing 8 years ago: I have a home which is still worth more than I paid for it (along with all the other advantages of owning a home), and I have a 2010 Camaro in the garage
