Buying A Used Versa

I keep reading threads where people are buying used Versas and then reporting problems with them. I bought my Versa used and followed a process to ensure it was a good purchase. First, always ask for the Carfax report on the vehicle to see if it was in an accident. Second, get an independent mechanic to check the vehicle out and ensure there are no hidden problems lurking. Third, I try to buy used cars only a few years or less old. My 2010 Versa HB I bought about 4 years ago was from Hertz Rent2Own. The car only had 21,000 miles so it was still under factory warranty. I got the car to drive for 3 days before deciding to buy. I made sure it had no issues such as weaving to one side and the engine sounded okay. I purchased my own Carfax for $15. Needless to say, the car has been running great. I had a CV Boot fixed under warranty, put new tires on it, and put new wipers on it. Recently upgraded my stereo. The car was listed for $5000 under blue book. Very pleased with my purchase.
