Theft arrest Boulder police say there may be more victims and are asking anyone who may have lost money after dealing with Go Motors or Gregory Kotsaftis to contact Detective Traci Cravitz at 303-441-3345.

Gregory Kotsaftis, owner of Boulder’s Go Motors, has been arrested on suspicion of theft and check fraud after investigators say he defrauded at least eight customers.

Boulder police said their investigation into Kotsaftis began in August when they received a complaint from representatives of a Canadian car dealership — Paul Motors in Montreal — who said they bought a 2011 BMW from Go Motors, 3200 28th St., for $65,000 and never received the car.

The dealership told Boulder police they contacted Kotsaftis numerous times demanding a refund, but when they received a check from him, it bounced. When the dealership threatened to inform police, Kotsaftis told them police involvement would only delay the process of getting a refund.

Boulder police said at least seven other victims are known to investigators, three of whom paid for vehicles they never received. Some of the purchases were made on eBay, police said.

Most of the victims confronted Kotsaftis and demanded that he return their money if he couldn’t provide the vehicle. According to police, refund checks for those victims were also returned for insufficient funds.

Boulder County District Attorney Stan Garnett said his office is investigating whether to pursue additional charges.

Kotsaftis, 45, turned himself in to police Sunday and was booked into the Boulder County Jail. He is free on $5,000 bond.

Kotsaftis opened Go Motors in 1996, specializing in used import cars.

A background check shows he was previously arrested on suspicion of theft and fraud in 2008. Those charges were dropped, and he pleaded no contest to one count of auto dealer-licensure offense, a misdemeanor. He was sentenced to two years of probation and 48 hours of community service.

Kotsaftis did not return calls for comment Tuesday.
