Yes and working on cars is a heck of a lot of fun as a result. Car modding and tinkering is a huge hobby and from what I can tell only supports these brands and the OEM sales. You need a Chevy in the first place to outfit it with 3rd party high perf parts. Something will break as a result and you'll be back buying more parts and investing even more in the GM/Chevy ecosystem. It's the opposite of how record labels try to attack music 'pirates' who also tend to spend more on music too. (Perhaps their love of music is what correlates high piracy and high purchasing? Hmm)

It adds to the romanticism and involvement. The original GT40 Le Mans car from the 60s that originally beat Ferrari was built from parts that you could go to your local Ford dealer and order. Maybe I'm wrong but I think that if you had enough money at the time you could actually buy all of the parts to build the same .427 they were using in the professional races. Pretty cool.
