There's a huge difference between Toyota and Tesla regarding quality control. Not even close.Tesla over MB every day of the week by a long shot. That's a poor comparison because European luxury cars don't last long at all anymore. They're money pits! Far less can go wrong with a Tesla and Tesla's have proven to be able to last much longer than any European vehicle with fewer problems, although it is a small sample size right now. There were a lot of naysayers when the first Prius came out and they've all been proven wrong about battery life. As a matter of fact the Prius is one of the most reliable cars on the road today and EV's will prove to be even more reliable. Refurbished Prius batteries have a very good track record for reliability. Sure the occasional one doesn't hold up but most do.
You're going to judge Gruber's work based on one person's experience? Or do you pull that out as an example to try and prove a weak argument against an out of warranty Tesla?
I warn people all the time about the cost of ownership of any European vehicle but I jumped at the chance to purchase a 150k mile Tesla.
