I have a friend who constantly tells me I should buy a new car.. My current driver has 150,000 miles on it, gets 21.9 mpg, uses absolutely no oil, and is extremely comfortable. Any new car the I might consider buying costs over $50,000 and gets 21 to 30mpg. I've been offered $2500 trade-in allowance for my car, and wonder if what I save in improved mpg will pay for the $47,500 new debt in any foreseeable time frame~!! Seems to me that I can buy an awful lot of gas and make some pretty expensive repairs to my car qith that much money~!!
