I would like some opinions from you thrifty folks! 
Right now I have a 7 year-old Dodge Grand Caravan that was bought used, still making payments on it. From the day we bought it, it has just been the biggest lemon ever. Without going into all the sordid details, it is just absolutely horrible. We could not enact the lemon law on it b/c we bought it used, but the dealer did send it back to Chrysler for 2 weeks at one point because it kept dying and nobody could fix it (still happens occasionally). It has been in the shop countless times, and cost us tons of money. We have a friend that is a mechanic so he gives us a break on repairs, but of course we do not expect him to give his time for free and we still have to pay for parts. It has about 80k miles on it. About a month ago we put $1k worth of work into it, yet again. It would have been $2k if we had anyone else do it, but like I said our friend gives us a break. Here we are one month later and a week ago I realized it was leaking all over the garage floor again.
I am just DONE with this vehicle. I'm so over it, I'm tired of pouring money into it left and right. My gut reaction when I saw that it was leaking again was to just cut our losses and buy something new. I have been looking at the new Kia Sportage. We could essentially break even on the trade with the dealer and our payment would end up being about $100/month more than what we currently pay for the lemon. I think we can swing the extra $100 without feeling the pinch too much, and I would have a 10 year warranty and finally be able to stop worrying about paying for repairs alllll the time. A big part of me wants to do this but I am not 100% sure if it's the right thing to do.
What would you do?
