I even had a satan-fuelled 2L autocratic Rover 75 tourer (estate) a few years ago; company car all-expenses-paid "runabout".

(alongside the S8; in fact I was having a "day out" in the Rover when my S8 was nicked off my drive

)
OK I had it "chipped" by Van Aaken (who remembers them?) so it was running about 180bhp and god-only-knows what torque.
It was always amusing to be sitting alongside Dell-boys in 3-series whatevers at the lights and leave them for dust!
The auto box with the remap was startling, and amazingly MORE fuel-efficient.
