I used to have a Nissan Skyline 4 estate. My trusted local indy told me to replace it and that it was going to cost me. I traded it at the local Ford dealer for a new Laser. The local butcher bought it but never bothered to contact me to ask about it first, despite my name being all over the handbook. I met the dealer socially about 6 months later and he told me that the car had cost them big money on warranty claims as the computer had failed and the fuel injection had played up. I replied that I was very lucky that he had talked me into getting a new car! It is buyer beware with second hand vehicles and even new ones can have problems.
