Because proper engines, that don't sound like the typical rattly sewing machine (or 4 pot Diesels that should really be in a tractor) motors as fitted to millions of automotive washing machines, are wondrous things.

Real engines make the blood flow, a V8 howling down the road brings out the small boy in grown men again, and nothing wrong with that.

Many hours of my formative years were spent in the signal box and on the platform at Welwyn North station, at a time when the Deltics with their massive 2 stroke supercharged Diesels would thunder out of the tunnel and through the station at 80+mph, stirring stuff for a young lad, the pleasure of that sound and power once learned never leaves you...i suspect the same is even more so for Americans brought up to the delicious sounds of V8's from when they could first hear.

I can remember the Commer two-stroke diesels carrying loads of bricks round Bedfordshire-heard them for miles.
