ok, As Leon has said, My Ae111 Blacktop Levin I had, I took out a driveright mechanical warranty when i bought it and would seriously recommend staying clear of them, I had nothing but hassles whith everything that went wrong on the Levin, Superstrut suspension X2 and apparently using 1 Litre of oil per 100km is usual wear and tear.
The warranty I got with the Subaru is awesome, Havent had anything major, but everything has been hassle free, Nil excess and covered up to the purchase price of the car.
I have had Diff seals and Rocker cover gaskets repaired twice with no hassle, The company is: Motorplus - I would highly recommend them.
Read the terms before purchasing any warranty, Most wont cover clutches for wear, Mazda rotaries, exotic euro cars etc.....
Most wont cover modifications unless they are stated at the commencment of the warranty so get it noted on your policy
