10K in gas melts away quickly. I know some people who have ran through that amount in six months. Also, you have to factor in frequent, expensive and time-consuming maintenance with either awful, cheapskate shops or the wildly overpriced dealership.

Also, it shouldn't come as a surprise, but if you're spending upwards of two to four hours daily sitting in traffic, you want it to be the nicest experience possible. Punishment boxes like the Mirage are desperation plays, and people upgrade as soon as they can.
