Hi,
Kev is right in what he is saying that the vehicle you want to insure is a high group vehicle and your age will go against you, however I have to say that even if you did insure it in your parents name with you as a named driver, if there is more than one vehicle in the family, it will automatically be rated on your age any way, so you would be better off insuring it in your name so that you could at least start earning the extra bonus on this vehicle.
Have you tried calling a local broker who would have the means to run all your details through, as they often deal with a varied amount of companies that would accept the fact you have 2 years no claims bonus on your other car.?
