on the civic, somewhere around $6-7k

on the truck, something like $200 on the rear suspension. My tires were $500, but its debatable whether thats "aftermarket." I also got a plastic center console/cup holder thingy for like $15. h:

On the infinity I sold the aftermarket 16's for stock 15's, so I guess that would be negative $75 on aftermarket parts. I plan to do the same with the intake.
