You owed 13K on your car and now you just went out and bought a brand new car w/ negative equity rolled into it. So now you owe $30+K on a brand new car, which you lost your shirt on the second you drove it off the lot. You more than doubled your car debt in a day.
You spend 5K or so on vehicle services throughout the last few years. You're sick of dealing w/ problems w/ the car and the "cost" of it. So your remedy is to go out and double your vehicle debt and cost yourself about 8K the second you drove it off the lot. I guess I'm failing to see "worth it" part.
Nice car, though. :)
