LOL, I used to have one of these:
1978 mustang 2 mach 1, T-tops, silver, black interior, 302 V8 with automatic.
Felt like it had at most 140 horsepower and still got only 16 mpg on a good day.
Plus it was tow-truck bait. POS.
EDIT: I just checked, it was rated at 140 hp. From a 302 V8. What a joke.
