Talk to your Rover dealer if you are under 50K and get a quote from them, it won't be cheap but it will pay for itself. I bought a 7 year 100K warranty with $0 ded. for $3000 and in 2 years it has paid for itself and I have about 40 K and 5 years to go on it. The are only a few aftermarket warrantys out there that will write policys on Rovers, check the web, if you don't find any I'll see if I can find an old one that I know some friends have used in the past.
Good luck,
