Congrats! I paid of my last car loan 2 or 3 years ago. Felt great.
Then I relapsed and leased a car (d'oh!). It was a "good" lease through my employer, 284/month, no down payment, 20,000 mile/year limit. I had the option to let go of the lease after 9 months, which I did without even thinking about it. Why did I get back into another car payment? I was lured by the shiny new paint job I guess.
I ended up paying cash for a 2 year old Chevy Volt to replace the lease, and haven't looked back. The Volt is a great used car if anyone is looking. Super low maintenance cost, and unless you drive huge distances everyday you will rarely buy gas. They depreciate quickly since they are "electric" cars - so you can usually get a heck of a deal, especially when gas prices are low.
