Putting aside the gargantuan visual differences between both cars. I could be blindfolded and my head placed through the open window of both cars, and the difference in the scent of the Karma interior and model S interior is shocking. The Karma smells like the inside of a Gucci store, while the model S smells like a Kia. Its has a very plasticky smell. Similarly blindfolded, running my hands along the interior of both cars, again the Karma feels more like a Bentley, and the model S like a Nissan Altima with a leather upgrade.
Seems like they've discovered that the large central screen and lack of a center console (not unlike a police car) may have been a design flaw, and they are now offering a console as an upgrade.
Why spend 100k on a car (tesla) with the exterior and interior appeal of a 50k car? It's overpriced, and it's boutique appeal won't. You may want to sell your Tesla stock at a profit, as many Facebook stockholder's wish they had. It's a flash in the pan car concept. As other car manufacturers (MB, Porsche, Audi, BMW) offer plug ins, the Tesla shortcomings will become more apparent.
