I did a little search after seeing this topic , to try and sort out my confusion and here's what I found out. The gas cap on the real car , and in the MPC ad, is on the left side of the car , yet the slot car version is moved to the right side! The motor in the real car is shown as a Ford Cobra which is on the valve covers and it is fitted with Weber carbs. I assume the slot version is a copy of this but can't say for sure.
