Ask admiral to confirm in writing the phone conversation you had with them, especially you asking them several times that all would be ok and that you would be properly covered.

The Opel GT was a US-designed/built roadster, the Pontiac Solstice and Saturn Sky using the US Kappa platform so not engineered for RHD, just like other US-GM models but re-badged as Opel for sale in mainland Europe.

GM claims to be a global manufacturer but in reality only Opel and Holden are capable of designing/building both LHD/RHD versions - and Holden closes next year!

I don't think you are being paranoid. Insurers can effectively do what they like unless everything is exactly standard bar anything you have told them about.

The onus is on you to tell them anything that could affect their risk. You have done your best, but they are judge and jury on this.

They have insured it as a VX220, on the implied premise that it is the Opel equivalent. Looking at it, it is nothing like a VX220. There must be many differences between your car and a VX220 that they can claim not to have been told.

Maybe it won't be a problem. Maybe it will. Admiral is not the most confidence-inspiring company I have ever dealt with.

The Opel GT is totally different to an Opel Speedster/Vauxhall VX220 - with no common parts - although the engine is an Ecotec it's a US-only version (normally) and not used in any other Opel/Vauxhall.

The VX220 used the Lotus Elise mid-engined aluminium chassis while the GT uses GM's US Kappa platform, which is front-engined steel.

Thank you all for your feedback. I've called them again and expressed my concerns and again they said that they "do this all the time" and that it comes up straight away on their system when they open they open my file that the car is an opel gt and not a vx220 and i've expressed concern on the phone multiple times to them however it will be fine... Ive asked for written confirmation of this as sugggested.

I will give it a go for a month with them (as its part of a multicar policy that is up for renewal in November) and it I get problem with Police pulls change it out to Adrian Flux.

Its not my main car, so I will not be on the road with it that often, but of course I take the feedback on board that it does not lessen the possibility of an accident.

Again, thankyou
