A) If your really terrible driving record is because you crash a lot, you probably don't want a Seven. :willy_nilly: And if your terrible driving record is because you get a lot of speeding tickets, a Seven isn't going to dissuade that behavior :devil:
B) Keep in mind that what other people are paying isn't necessarily relevant to you, there are too many variables involved, a 60yo man with a perfect record living in Alaska isn't going to pay anything near what you with a bad record and living in Los Angeles is going to pay.
That said, I have a Superlight R like the one you are looking at and live in the westside of LA and I pay $810 per year from Hagerty and that is for "limited use" and insured for $40k. BUT I am 39yo, never had an accident and haven't had a speeding ticket on my record in 10+ years, so figure you will pay a lot more.
C) The insurance companies can't find the VIN because Caterham isn't a registered manufacture in the US and under the CA SB100 the CHP assign a VIN to it.
Also there is some funky stuff going on with the car you are looking at (if it is the one I am thinking of), I had been contacted by a couple of people looking to buy it and the owner appeared to be playing games and less than forthcoming so they backed out of purchasing it.
