Am I understanding correctly? You are putting audi A4/3($27K MSRP) into the same class as Jaguar(starts at $47K) and Range Rovers ($83K MSRP)? I think Tesla with it's price tag should go into a separate category from audi a4,3...
Edit: According to wikipedia (https://en.wikipedia.org/wiki/Car_classification#USA.2C_UK_a...) - the British English "Luxury Car" is represented by: Audi A8, BMW 7 Series, Jaguar XJ, Maserati Quattroporte, Mercedes S-Class.
