Yes! Exactly my feelings on it too. I do like the new interior though - so if they could give the upgrades to that and the motor with leaving my original exterior I may be interested... if I can figure out how to come up with the additional cost.
Typically boutique car makers like Tesla is (at this point) will put together a custom mix and match car whatever way the customer likes. At 100K it's only right.
Personalizing is easier for them than the manufactures putting out a dozen cars a minute. The big faceless companies only offer two or three models and you are forced to buy the entire "sport" or "luxury" model to get specific feature you want like a built in Nav system or special wheels.
Tesla would do well to limit the Sport's visual exclusivity to just a paint color like they did the Signature Green.
