Had an interesting experience at the local Audi/Porsche/BMW dealer today. I was looking at an Audi S4 and asked them if they were interested in taking in my 2014 Model S. The answer was a resounding no. The value was "too unpredictable" at auction for EVs according to the GM. For example they had recently taken in a Volt, sent it to their auction reseller, and the auction house offered them $1 for it. That's right. A dollar. Now before everyone piles on the dealership, keep in mind these guys want to make a buck and would take anything in on trade if they thought they could make money on it. They had no problem losing a sale at the thought of having to deal with a Tesla trade-in.
