While I prefer a three years mf warranty, surely if an insurance backed 3rd party warranty lasts 4 years, and covers more parts than the mf warranty, then this has to preferable to a 1 years mf warranty? I agree that the chances are it will only cover up to a certain value for each part, but thats down to individual policies. Im not trying to start an argument, Im just trying to find out if my brother is wasting a lot of cash on this warranty.
At the end of the day the cars come off the same production line so should all come with the same warranty. Its just a scam by renault really.
