Hmmm, struggling to remember any decent RAF MT Vehicles in my time. Probably the best were the Austin 1800's until the Montego Turbo Diesels.
Between those were a mix of horrible Vauxhall chèvettes in puke green, black Metro's that were even worse, the odd Ford Escort Estate Diesel in Black. Sherpa minibuses in various colours to deceive the IRA! And at least the SWB and LWB Landrovers which you knew what you were getting with an inch and a half steering play before the front wheels responded to any imput!
They were fun to drive on any long run Not!
Still, at least they didn't spy on you!
