Keith Snyder, 30, who spent Sunday afternoon advertising his SUV at the side of Interstate 70 and Quebec, said he was inspired by companies that advertise at the roadside, KUSA-TV, Denver, reported Tuesday.
"I put an ad for my Jeep on Craigslist and I put a sign on the Jeep and it just hasn't sold," he said. "I see people advertising for their companies on the side of the road, so I figured I'd give it a shot."
Snyder said the vehicle has become too costly to keep fueled.
"I'm spending about $74 to fill it up," he said.
He said the fuel efficiency of the Jeep is likely one of the major obstacles to selling it.
"My Jeep probably gets 15 miles to the gallon," he said. "People want 25 miles to the gallon."
Snyder said he is asking $2,500 for the vehicle, well under its Kelly Blue Book value of $3,100.
