Well there will be someone that will pick up the slack on warranty repairs. We only have two AR dealerships in AZ. If one closes I hate the thought of going to the other dealership. However the one we go to does sell FCA (Fiats, RAMS, JEEPS) so even if they stop selling ARs they will still service them since they have the equipment and do a strong used business on all makes. The dealership won't go out of business but it doesn't depend on Alfa to survive nor FIAT. Doesn't mean that they will always sell them.
Right now after having the 2017 for over a year we still love the QV and wouldn't trade it for anything so all we care about is servicing. We have the 10 year Warranty so for the next 9 years we will continue to enjoy. We have so far had good luck and I do hope the best for Alfa cars. My Bimmer sales guy sent me the Jeremy Clarkson link and watched that like a proud parent. We get into the M3 vs Alfa convo and I told him I will let him take the QV for a spin. You have to drive it to appreciate it. Not the bells and whistles M3 but it is awesomeness. The X5 50i is a very nice car and I could put a pillow in the back and fall asleep on long drives it is smooth and comfy but NOTHING NOTHING in comparison. I do like the HUD but don't miss it in the QV. Actually for all its missing tech, I miss nothing in the QV that I don't have. I actually don't care.
