When I lived in Colorado, I often ran the Mercedes 280CE coupe (182 hp) up to 100. Once was on a string-straight, well-paved county road near Great Sand Dunes National Monument. I'm roaring along, alert to the nines, when I come over a very slight rise and see a sign:
WATCH FOR BISON ON ROAD
I slowed down quick.
The W126 Mercedes, with 201 hp, I ran up to 100 several times, once in NE New Mexico along the highway that parallels the old Santa Fe Trail. Wide open country and a smooth highway. Wow.
Maybe those 2 cars would have gone faster, but I never got the chance to find out.
