Power doesn't necessarily make it more fun to drive. Some of the most fun i have driving was in a metro 3 cylinder. BALLER
I would much rather have a 200$ justy than a dual cam ka from 91. Not saying its not a good lil motor. Just would rather have the mad respect from the ladys of owning a justy.
There are deals out there if you feel comfortable with working on a horizontally opossed motor.
