Does anyone know of any warranty program that allows the buyer to choose what items they want covered?

I am looking for something that I can, for example have cover ONLY a high pressure fuel system, turbo, transaxle, and DI injectors.....reason being is I've always wanted to own a diesel car but there is no way I am risking a VW DSG blowing up on me or the infamous CP4 fuel pump wrecking 5k+ in parts when it fails. This is one of those instances I would not feel like dealing with any of this breaking myself so I thought I would look into a warranty but none I have seen allow me to pick what I want/are pointless since they would cost more than any fix would. Older cars are rust traps so I want something newer than 2010.....when the ES is gone it will be able to cover the cost of this endeavor but I am starting to look around now. I have found one car that is appealing since it's a hatchback and would be able to carry a decent amount of stuff/be useful.

I swear I don't have problems.
