Just as the subject suggests...
Me and a friend were talking a little while back. We came to the subject of dealer parts prices. I mentioned, what do you think the markup would be to buy every single part(down to the individual nuts and bolts) to build a car from the ground up using only parts purchased at a dealer. I searched for the better part of 20 minutes and found no previous attempt or even mention. It would be interesting to find out. Thanks Jerritt
