It seems that most projections have the $7500 credit ending in June 2018. My delivery estimator shows July 2018 as best case for AWD. So here is what I'm thinking of doing: Buy the RWD Model 3, probably with few or no options, in my Dec to Feb window. Trade it on AWD Model 3 when it becomes available. Effectively I get the tax credit benefits, and I would expect the resale value to be robust. Any thoughts on this idea?
