I have a 2010 III with 54,500 miles. My lease ends in June and I have the option to buy the car at a very good price.. less than 11K. I am thinking of buying it, but I wonder what major expenses it could end up costing me in the next 5 years that would make it a bad idea to buy it? I like to lease cars for only the length of the warranty, so this would be my first time owning a car without a warranty. Thx
