Smallest was the first car I bought with my own money...a 1980 Dodge 024 that averaged 50mpg. We've come so far
Largest was a Suburban when I had 3 kids & we liked to camp a lot. Got maybe 8mpg. Lol
Favorite? I've had 2 Oldsmobile Auroras that for me were "all that".
Smallest was probably a 1980 Mazda RX-7. Largest would be a toss up between a 1972 Dodge Tradesman 200 long wheelbase van, and a 2012 Ram 3500 crew cab long bed 4x4 pickup.
