Spence, you’ll need the cash, plus provide them proof of ownership (v5 should do it) and (if you can) a pic of the vin number on the car (ie that you’re not trying to clone off the v5). They may still offer the data cards out of Germany but the US is the same but they’re really used to us lot!
The VIN should also be stamped on the right hand side front longitudinal frame in the engine bay. It’s under the large diameter duct pipe from the air filter
VIN 113 042 is 230, 113 043 is 250, 113 044 is 280
