"We sincerely apologise for any inconvenience caused and would like to thank everyone who participated in the Top Gear Track Experience over the last two years - for their custom, enthusiasm, for great feedback and support."

"We deeply regret the position this puts our remaining customers in, have posted refund advice on our website and will be contacting all our customers directly in the coming days."
