Simple - Insure it as a 2.0L Sierra Ghia lol. Go on one of the insurance comparision sites and type in your reg. (Compare the market or money supermarket.com) Should come up as a Sierra saphire 2.0L Ghia. Has done on every cosworth reg I've ever typed in. When the pigs see you, they just think its a nipper in a sierra cosworth rep. The average cop going to be able to tell the difference between a genuine cossy anda really well done rep??... Don't think so.

There are a couple of downsides to it obviously... your car is stated as a cossy with the dvla, but this has never seemed to of mattered before. Obviously if you wipe out or crash, don't expect to be payed out much, you just have to hope whats left of your car is enough to make up the loss (which with a cosworth usually is,beings as they are worth more in parts anyway).

Of course i'm not stating that me or anyone I know has ever done this.... it is highly illegal and very cheap 2!
