Going slightly OT, for which I'm sorry. Aco mentioned Bentleys, presuming we are talking about "proper" WO Bentleys, before RR took them over.
When I lived in Southampton I regularly used to see a real 3.0 litre and it looked huge alongside the cars of the day, it was 1961 to 64. Well one day I was on foot, one foot, as I had a leg in plaster, waiting to cross the road which was a 4 lane road out of town. There was a gap in the traffic, me and my crutches scooted 1/2 way across, then I saw matey in his 3.0 litre, coming towards me in the outside lane overtaking some stuff on the inside. I reckon he was about 2 feet away from me when he went by. Going by the other traffic he was doing 45/50 mph. It sounded like it was idling, revving soooo slowly, and the exhaust noise was fantastic, not loud at all, it sounded like rattling a big stick around inside a metal rubbish bin. I'd love to see and hear one going quickly, no wonder Ettore Bugatti described them as "...the fastest lorries in the world"!
