I don't think even the Quentin Wilson warranty wise one is worth it. If you look at what's excluded:
Worn Out Parts (as defined)
Any Part that has not suffered a Failure but which is simply recommended by your Repairer to be replaced as good engineering practice or in order to avoid any future potential Failure.
Any Parts normally replaced during the manufacturer’s recommended servicing of the Vehicle such as: spark plugs, high tension leads, lubricants, fluids, filters, wiper blades, fan and drive belts (not a complete list) also including: pipes, hoses, fuses, bulbs, connectors, wiring, batteries, wheels, tyres, tyre valves and tyre pressure sensors, frictional materials of brake linings and clutch plates, exhaust systems, other than for Parts under any included Addition or unless any such items are, at our discretion, authorised within the costs of a valid repair providing the Vehicle is not within 1,000 miles or 30 days of its next scheduled service.
The Failure of any Part with inherent well publicised manufacturing defects or requiring replacement due to it being up-dated, superseded or which has been recalled by the manufacturer where you have no proof that the recalled Part has been previously replaced.
Any Part which within the last 12 months has been the subject of a previous repair.
And that is a mere 5 excerpts from the 36 points of exclusion.
