You know what, all car manufactures will have problems along the way. And I'm sure that if something happens along the way that VW "will" take care of you while under warranty.
No car line is perfect. Be thankful you don't own a Toyota right now!!!
If you are afraid of challenges along the way... don't buy the car.
I'm "all in" with the Golf R. I'm buying it no matter what. I've owned several VW's since '77 as well as other cars. My passion is in the VW line. To have this much "OEM" power in a VW is great! I'm ready to mod the hell out of it once I have it too. I also have a mod friendly dealership as well. Giddy up!
