not sure where andywert's going with this, but I was comparing two of my former rides with my future ride to get an idea where the smart sits.
each of these were my only car at the time, all were acquired near-new (~7k miles) and all were driven extensively, city & highway.
1970 Subaru 360:
rear engine / rear drive
seats: 4
wheelbase: 70.9"
length: 117.7"
width: 51.2"
height: 54.3"
weight: 900 lb.
0-50 mph: 37 seconds
mpg: 40 / 50
1976 Renault R5
front engine / front drive
seats: 4
wheelbase: 95.7" (more or less, L /R wheelbase was different)
length: 146.6"
height: 52.9"
weight: 1600 lb.
mpg: 28 / 40
2008 smart fortwo
rear engine / rear drive
seats: 2
wheelbase: 73.5"
length: 106.1"
width: 61.4"
height: 60.7"
weight: 1808 lb.
0-60 mph: 13.3 seconds
mpg: 33 / 41
So, I think I'll be right at home with the smart. the height will be a noticeable difference, though.
