Diffrent cars use diffrent part numbers, thus they are not the same wheel. It is the same as saying why is a 245/45/17 brand x tire #100 a diffrent price than the 245/50/17 brand X tire #100. It is not biased one way or another by marque of vehicle, some applications are just plain more expensive to build so the manfacturers charge more for them. Hope that helps. If you have any other questions please let me know, thanks Aaron 800.428.8355 x395
