I've also been quite lucky, I work as a mechanic at a dealership were we sell Ferrari, Aston Martin, Lamborghini, Maserati, Jaguar, Land Rover, Alfa Romeo, Fiat(!), Lotus and Ford F-trucks. But the most expensive car I've ever driven for a substantial amount of time on the road would either be a Aston Martin DBS convertible or a Lamborghini LP570 Superleggera. But most expensive car I've driven EVER (only across a parking lot lol) is a brand new Rolls Royce Phantom =D
