There’s ~3% built into msrp for the dealer. Then there are kick backs from banks they are pushing you to finance through. Then there are extras that are basically 100% profit. Then there are dealer installed options. How much can they possibly be expected to make for providing parking space? Dealers are absolutely fucking useless outside of test drives. Every cent over msrp is basically theft.

Who takes a used car to dealer for service? Are you saying they make more money on used cars because they can price gouge more effectively?
