The girls bring in two vehicles in this one, with a Mercedes GLC getting some new suspension and other bling, and a really cool BMW Z4 that needs some maintenance under the hood.

For the first time, the girls get to work on a rotary-style engine by bringing in a Mazda RX-7. They'll take the rotary engine apart to show how it works, and install a new clutch on the Mazda to get it running again.
