Devon, PA — One is the car dealership of the future. One isn’t. Both sell electric cars.
 On the western edge of Philadelphia’s Main Line, sits a rare Tesla dealer-plus-service center (most Tesla locations are simply stores – which are, in themselves, pretty rare).
 Within five minutes, you can drive to a Chevy dealer that (sort of) sells Volts (technically a plug-in hybrid).
 It’s a radically different experience. Tesla offers a glimpse of the future while the Chevy dealer is more like a drive down memory lane.
