Jefferson family's car

Robert Jefferson’s car, is the Jefferson family’s car. It’s painted white, and has heated front seats. It’s only appeared in “Diary Of A Wimpy Kid: The Third Wheel.”

The Third Wheel
It first appeared in The Third Wheel when Greg, Abigail, and Rowley were going to the Middle School Valentine’s Day Dance. Rowley and Abigail start saying things to each other and as said by Greg, "giggling like a bunch of 4th graders" and not knowing what it was about. Greg, Abigail, Rowley, and Rowley’s dad arrive at Bob’s Vacuum Repairs, to pick up Robert’s vacuum cleaner. When the car arrived at the Spriggo’s parking lot, Robert opened the car’s back end for Greg so he’d be able to get out. But when he got out, Greg’s pants and suit coat were covered in grease stains from Robert’s vacuum cleaner. He had to borrow another jacket that had never been washed, and Greg eventually decided to leave after being unable to handle the smell of body odor. The group went to Corny's Family Style Restaurant, with Rowley getting his tie cut due to Greg not warning him about the rule in time. Abigail and Rowley rack up a SUPER high bill by ordering appetizers, expensive menu items, and extra dessert, which makes Greg annoyed and lose his appetite after his burger order was wrong. Finally, the group arrives at the Valentine's Day Dance. The theme this year was “Midnight In Paris." But it wasn't too pleasant, since people were drinking chocolate right out of the chocolate fountain and lost half of the gym to some senior citizens who’d rented the gym 2 months earlier. Michael Sampson arrived after the meeting was over with another girl, which made Abigail start crying very hard. Greg tried to calm her down, but over-reacted when he thought she had chicken pox after seeing a pimple on her neck. But on the way back, she and Rowley become a couple which is mentioned by Greg at the end and shown when Rowley takes Abigail back to the front door.
