My 15 is out of warranty, I've had the call from BMW and having spoke to them here's where I'm at. Warranty can be purchased with a ?100 excess for about ?31 ish at a special price just now . I said I don't ride all year round so would I be able to cancel in October and renew again in April? Yes was the answer but not at that rate , ok how much then , about ?2 a month more. Sounds like one of those too good to be true deals or am I missing something?
