Is the car paid off? Once a car is paid off, you have to spend way more than $2000/year before it financially starts making sense to get a new car. $2k/year works out to about $167/month - you're not going to find a comparable level of automobile for that amount in car payments.

If you WANT a new car, that's a totally different thing. Then it doesn't make sense to be putting money into a car you'd rather not keep.
