Liza Biggs' is boiling over like the red-hot radiator of a van crossing the Mojave Desert. She's just seen the bill for the repair of her van and she's livid. Liza marches into the garage to see mechanic Carlos who's worked on her engine. He is in for it now. She wants that price lowered.

As angry as Liza is, Carlos makes no attempt to calm her down or change the price. Liza sees he's not going to give her what she wants. She decides to switch her approach from battery acid to honey. Slowly he begins to cave in. She turns on her high beams and blinds him. That does the trick. He's a sucker for what's under her hood and now very eager to handle her dangerous curves.

Renegotiation of the bill takes very little time. The office girl doesn't need to know. He's boob-drunk over the Biggs' rack. Carlo's transmission fits snugly between Liza's huge mufflers and her expert oral argument sends him into third gear. They can settle this right there alongside her van and then in the back of it. They go for a ride and have a blast getting to the finish line. Buxom female customers are always right, especially when she's Liza Biggs. Please fasten your seat belts.
