Ferrari warranty company advice.

I have been looking at some warranty companies and I have found one called Warranty Works who have offered me a very good price to cover my ferrari 360 for 12 or 24 months on a Motorplan Warranty which is used by the trade.They have sent me an information pack and it all looks very tempting,but I am aware that a lot of aftermarket warranty companies look for a way out when it comes to paying for repairs.
I know a lot of you will say keep your money and pay for repairs as and when,but I would like to hear from any member who may have some experience with Warranty Works/Motorplan which is administered by a TWG Services ltd in Harrow.I appreciate any advise please.
