In evaluating a preowned vehicle I ran into something different. Vehicle registration and factory list the vehicle as a 2000. Carfax and factory lists the chassis as a 1999 chassis. Factory ( a very reputable manufacturer) indicates the vehicle was built at the beginning of the model year on a previous year's chassis and this is not uncommon. Since chassis' don't change much and assuming this is not uncommon at the beginning of a model year, I tend to think this a minor issue. Any opinions/experiences?
