Dale Earnhardt Jr is off for a couple weeks with concussion-like symptoms and is filling some of his time to sell a few of his personal vehicles on eBay.

Jr. is offering a 1973 Chevy Camaro, ’02 Chevy Camaro, ’10 Chevy Camaro, ’94 Jeep Cherokee, and a Street Legal Stretch Golf Cart. He promoted the auction Friday via his Twitter account.

Alex Bowman filled in for Earnhardt last weekend at New Hampshire after the surprise announcement of Earnhardt’s illness just a couple days earlier. Recently retired four-time NASCAR Sprint Cup Series champion Jeff Gordon will drive the No. 88 this weekend at Indianapolis and next week at Pocono and may fill in further if Earnhardt is still unable to drive.

Earnhardt Jr. updated his condition Friday, also via Twitter, saying, “Today is the 1st day in many that I sensed improvement. Seen small gains during my physical therapy as well. Light at the end of the tunnel.”
