ARDS for a 21st birthday present advice

[Dazzla100]

Hi everyone,
My son turns 21 in August and he plans on getting a track car as soon as he can afford one.
He’s had some limited experience in the past on track such as a day at Hethel in an Emira and he’s driven my Exige around Silverstone.
I want to get him the opportunity to get his ARDS licence and I’m looking for advice on the best place to do this. He would need to go somewhere that supply’s a car.
We are based near Nottingham but travelling isn’t an issue.
Any advice would be appreciated.

Thanks
