What about.....

1=colt
2=lancer
3=380
4=pajero

or something like that...colt is 1.8l? so it'd be like a mitsubishi 180
lancer is 2.4. so 224
380 with 4cyl will be 324
pajero is 3.5? so that'd be 435.

Just some crazy idea I just came up with This idea wouldn't hold and I know it, I just thought it'd be funky to think about.
