good call i forgot about the electronics.
I second red65mustang some of the "ricer" cars do pretty good.
from the factory in 1988 a Monte Carlo SS came with 180 horse power from a 5.0 liter engine and got 17 mpg city and 24 on the highway.
in 1990 the Mitsubishi eclipse GSX came from the factory making 195 horse power from a 2.0 liter engine and got 20 mpg in the city and 25 on the highway.
I still like my Monte Carlo though...i know from experience a 1990 GSX doesn't stand a chance against it now.
