They said something about it being only for the first few customers. Not sure how many, I'd take a guess it would be the first 30 ish. My car is a 2.0, so I guess its not just for 1.0 customers.. however my dealer said I was "the only 2.0 car they had received" which was most definitely a sales tactic.
The jacket is made specifically for Galpin, it has giant "Galpin Lotus" lettering on the front. But I wouldn't doubt other big dealerships with some sway may have their own versions. It's honestly very high quality, made by the jacket company Jeff Hamilton, so probably costs like $400-$800 for regular purchase (I'm sure they got some deal or Lotus sent it directly to them or something).
