Colin, the dealer you buy the car off give 12months the rest is which ever manufacturers auto you buy. Yes you can have them under the dealer contract although some are already trying to shirk that responsibility. I know this from a friend who has an MG , recently bought and the dealer dosn't want to know. I know if I was about to purchase a new vehicle, I would like the longest warranty I could get as I have had claims over the last 3years on my car although minor, that would have come out off my pocket and not the manufacturer if the warranty was less than 3 years. The other point is, where is the spares going to come from? Some come from Independant manufacturers, some are patern parts which will become scarse. Steer clear until the road ahead becomes clear. I know this dosn't help the Rover group and its employees, but they won't pay for any repairs etc if you end up with a dud which can happen with any car.
An end to my ramblings, Brian
