I'm not impressed with modern styling trends. Tesla have little styling history of their own, but they've got the entire history of the automobile to borrow (or steal) from. So, why mimic the generic, forgettable, sort of chunky style of most cars on the road today? I say, take the most beautiful classic car designs ever made, slick them up, and re-badge them.
As far as two seaters are concerned, nothing else is as cool as the 1970s era Corvette Stingray. 45 years later it still looks like the future. Put it through the wind tunnel, replace all the creases and sharp edges with curves, and make it your own. (There was, in fact, a car designer in Europe some years back who did this. He built a custom Corvette with the melted-curves treatment. It was aerodynamic, it was fast, and it was beautiful. And I can't remember his name, and Google is no help at all.)
If the proportions of the Stingray don't seem viable to achieve kind of packaging that we're looking for (with that looong hood and the cabin scrunched to the rear), then I might suggest the 1990s era Pontiac Firebird as another worthy design to emulate. It was always a strikingly sleek and semi-exotic looking vehicle that I think only suffered because it was never able to completely shake the cheesy associations that earlier design generations picked up from Smokey And The Bandit and from Knight Rider.
Oh, and you'll notice both of these cars have pop-up headlights. What ever happened to pop-up headlights?
