I foresee a market for dipsticks coming. Add on kits to give your car something that others don't.

Find a place in the lower block, drill a hole, tap it out and install a dipstick tube and stick from an old 240D.

Fifty years from now kids will look at old cars from the early 2000's and point to the dipstick. Then they will ask their Fathers, "Hey, what's that thing for?"
