I say if you've paid down all of your debt yes, go ahead & treat yourself. If you are still battling with any credit issues this will only exasperate this situation and tie you up for another 5 years. I myself would love to buy a new car tomorrow however with the house & debt I know its just not the best thing to do right now. I'm pretty sure you can make the right decision on your own without anyone needing to tell you.
Good luck!
