This sucks for those RS owners but at least they should be able to sell them for a decent price and put that money on a Golf R or Civic Type R.
I haven't heard of many engine issues with the Golf R, even tuned the failure rates are really small.
I think as stated that Ford is more than capable of building a reliable and powerful engine, but someone decided it was okay to cut corners to save money. Kind of like what VW did with their TDI engines, but at least those over performed in every way other than emissions.
