We have a major car problem, heat out at the house and various other things happened all at once! We need dependable trasportation. A dealer called me to let me know we could get a 2010 Certified Used car with 24k miles on it for 14k bumper-to-bumper to 100k miles. It is the security we need. We WERE saving to buy a $10k car cash, but after heat, roof and car crapped out - impossible. Is this stupd inpulse - or smart security and pa off in 4 months? Input please!
