Jess, I've got nothing against any of the cars that you mentioned, but the way I see it, When the Air Force orders a Fighter Jet, and it's a lemon, the company that builds them doesn't replace it with a cargo plane.
In other words, you bought a 2 seat sports roadster for a reason. (you live in paradise and you enjoy top down driving) and as far as I can tell, none of those cars fit the bill. I'd tell them to order you another one from the main land, and in the mean time, give you a super short term lease until your new car arrives.
