He’s not here to crash your wedding or overstay his welcome as a house guest.

Maybe just shake up the dealership experience a bit.

Actor Owen Wilson, star of such comedies as “Wedding Crashers” and “You, Me and Dupree,” has teamed up with EchoPark Automotive to be the spokesperson for the used-car retailer’s largest single-brand marketing campaign to date.

The ad campaign, which kicked off Sunday during NFL broadcasts in EchoPark’s markets, has Wilson walking through the various frustrations that can arise when a consumer tries to buy or sell a used car, before contrasting those with the EchoPark approach focusing on “quality vehicles, compelling value, and a happier experience.”

“The idea of getting a good car at a fair price hits me right here,” Wilson said in a news release, referring to his heart.

“I’ve definitely found the car-buying experience stressful in the past. EchoPark is about great cars, at great prices, sold by really great people. So, I’m excited and revved up to bring this campaign to life.”

The campaign will be run across TV, streaming, online video, social media, digital display, streaming audio and outdoor advertising. One goal is to increase awareness of the used-car retailer, which is part of the Sonic Automotive family.

Along those lines, here are some statistics that may leave you saying “Wow!”

EchoPark says 93% of its customer reviews are five stars, which it says is the highest proportion of any national vehicle retailer. But EchoPark research indicates only 15% of shoppers know the brand.

However, once they understand the “quality, value, and guest experience” offered by EchoPark, consideration increases 14 times, the company said.

“We have built a brand that delivers outstanding cars, exceptional value, and an experience our guests overwhelmingly recommend,” said David Smith, chairman and CEO of Sonic, which is EchoPark’s parent company. “Now we need more people to know what they’re missing.”

The new spokesperson can perhaps move some cars at lightning speed.

“Owen gives more people a reason to discover EchoPark. Our job is to make sure they’re glad they did,” Sonic president Jeff Dyke said. “That means a great car, a fair price, and teammates who make buying easier. That’s how we deliver on ‘Every Car, Happy Owner.’”
