Wouldn't say finding parts is impossible just yet.. here's my logic.
5 year warranty= about 50k miles put on in 5 years. End of warranty will be around 110,000
Coils will have to be done in that time, will that warranty cover it?? How would you go about replacing it through the warranty all at the same time which is how they need to be done...?
Cooling system seems to be problematic around 100k. Figure $1000 for that. You might or might not still have coverage for that, this will probably need to have a deductible. Im assuming its covered..
Are suspension parts covered.. Even if they are, around 100k miles seems to be the golden time for that. Will you still be covered?
Any other miscellaneous parts seems to go out past 100k, I heard of an ac compressor going out on an 06. Warranty will probably be up before you have problems costing over $1000k again.
Just my opinion. If I ever were to go about buying a warranty, make sure all the problematic items are covered.. Dccv, cooling system, coils, suspension( doubt it), charging, ac, etc... I doubt you will ever pay 3k in repairs in 5 years not including maintenance and wear/tear items. (I get the 3k, including the probable deductibles you will be paying)
