Do you need another car at the moment? If you entered a competition and won a car prize, what would you do with the car? Would you sell it or use it yourself?
We have two cars right now but one has over 100,000 miles on it so we would keep it. I would give it to my husband since he drives the one with high miles. I tried winning him a car during the time Conan was giving away the Chevy Cruz's but no luck.
It's hard to say, really. It would depend partly on how much the taxes would cost to get it registered! It would probably be more cost-effective to just sell it, if it were a new one. Plus, I tend to prefer older cars.
I used to dream of winning a car when I was younger and didn't have my own. Now I think it is almost impossible to happen to me. Anyway, I would tend to sell it also as we don't need another car now.
