I just had my car appraised at CarMax. I did it because I live in a state that charges property tax on vehicles. They assessed my car @$37K and I complained that it was too high. The tax assessor said that if I take it to CarMax and bring back the written appraisal they will accept that as "wholesale" value and add $3,000 to the appraisal to bring my car to "retail" price - which is the basis of the tax value.
My car is a 2014 i3ReX, Andesite Silver, HK Stereo, Park Assist, Giga World, car mats, Technology package, DC Fast Charger, 6600 miles. CarMax appraised it at $26,000. The sticker was $53,750. That's quite a hit. Luckily I'm leasing. The lease ends in February 2017. Not sure what the car will be worth then, but given the current value it appears as if it will wholesale under $20K at the end of the lease.
That's an interesting price point. I wonder what BMW will do with 2 year old loaded i3 cars, likely with less than 20K miles competing with 2015/2016 cars (likely many leftovers) and a 2017 model that gets better range than the original cars.
At the right price I'd be interested, but will be more competitive with the Bolt/Tesla 3 and other choices.
