Extended warranty (aftermarket) and MINI Extended Service Contract are 2 different animals.
I paid $1,350 plus tax for my 6 year/100K mile scheduled service extension for my '05 MCS. Best money ever spent. Used it for the first time last week to get the rear brakes of the car replaced
I will get it for the Clubman in a couple of years. It can be purchased at any time during the first 3 years or 36K miles of the car from the first "In service" date.
Some dealers markup the extended service contract. Unfortunately you can not purchase it from a remote MINI dealer as the car and key (which must be inserted on a reader) need to be present at the time the service advisor issues the contract.
