I wrecked my car 2 weeks ago and I needed a new car. So, I went on craigslist and found a 2008 cooper convertible with the sidewalk package. I did a quick search on what sidewalk pkg meant and said it had sport pkg + premium pkg in the car. In my stupid head i was think sport pkg = cooper S. But in fact it just leather seats, radio system, some trim and a unique paint job.

so i test drove it and bought it on the spot bc i really needed a car and i liked it. it has 43K miles on it, i payed $15. in great condition. Has 50K dealer warranty.

I payed below KBB value (about $18k). Should I sell it or keep it?

Thanks!
