My 2014 Model S 60 has already been through one door handle replacement (left rear) for which the local service center didn't charge me anything even though technically my car was out of the 4 year/50000 mile warranty period. Yesterday when I took the car in because the right (front and rear) door handles wouldn't open, I was told the cost of replacement would be a little over $1400 but they would waive the labor which would bring the cost down to $1100. I read in this forum that door handles can be had for $200 on ebay so I checked it out and sure enough, there are pre-owned door handles available for under $200. Will a non-Tesla authorized auto shop be able to install these for me? Can someone recommend one in NJ (I live in central Jersey) ?
