Evolve's M3 kit is beautifully designed and Sal has beaten the crap out of it on the dyno to wring out as much "area under the curve" as possible! This is an instance of where you get what you pay for really is the case...
while this is true, most A/M parts do decrease in cost relative to model year depreciation as well. Here you have an expensive mod that is 1/3 value of the car in a used market.
