Osborne and Dunlap hope the dealership eventually will be able to auction off the car to benefit Love Hope Strength.
Six months ago, Schomp Automotive donated a similar Mini Countryman for the charity's Manhattan office. It plans to donate a third car for the Los Angeles office.
"We're working with Capitol Records to get another car out there [in the lobby], so when an artist comes to Hollywood we can get the Elton Johns and Katy Perrys of the world to sign it," Osborne said.
Helping Love Hope Strength costs about $25,000 a year, Dunlap said. Osborne estimates it has led to at least 20 extra sales a year. Schomp Mini sells about 1,700 new and used Minis a year, while the group sells about 11,700 new and used vehicles a year.
But increased sales are only a small part of the reward, Dunlap said.
"It's really powerful because we can go back and look at a concert last summer and see that we found a [bone-marrow] match for a guy in Boston through this, and he's still alive because of it," Dunlap said.
In 2012, the dealership started a partnership with Burton Snowboards.
Burton Snowboards attends skiing and snowboarding events in Colorado and Utah, posting about those events on social media, Osborne said. The dealership gave Burton three Mini Countryman cars with Burton's name and Schomp Mini on them. The donated cars cost Schomp a total of about $20,000 a year, mainly for depreciation.
Burton gets to use them for free as long as the cars are on display at the ski events and on Burton's social media, said Osborne.
"The cars go all over the place" to big ski events, Osborne said. "There are tens of thousands of people who ski every weekend and they see our car with our dealership name on the mountain."
That deal has led to at least 15 more Mini sales a year.
That same year, Schomp chose to sponsor the Underground Music Showcase, a large music festival in Denver featuring up-and-coming acts, at a cost of about $40,000 a year. The dealership's name is prominently featured at the festival along with Schomp's display. Last year, the dealership also provided a fleet of six Mini Countryman cars and drivers to get UMS concertgoers home safely, Dunlap said.
Dunlap said all three partnerships have helped the dealership market both itself and Mini for a nominal cost. And the benefits go beyond sales. "It's one of those checks you don't mind writing each year,' he said, "because we get a lot of smiles out of it."
