Walker, who also sells Ford and Volkswagen vehicles, said his Jeep sales made up a quarter of his business. He said he would have to lay off workers and said he believes the company targeted his showroom because he shared his showroom with competing companies.
"We can't continue to employ these people," he said. "It was a profitable business for years. When you're off 40 percent from where you were four years ago and now you lose 25 percent of your business, it hurts."
Walker was on Capitol Hill Wednesday, along with more than 100 other dealers, to convince lawmakers to stop the automaker from shuttering their stores.
In addition to the 789 planned closures, Chrysler has lost 400 dealers since early last year.
The U.S. Treasury Department said in a statement that the move to close dealerships was "one of several steps the company is taking to restructure to achieve financial viability."
In its statement, Treasury said it had no role in deciding which dealers would be shut down. The government said dealers, like autoworkers, had to make sacrifices to keep the industry viable.
"The sacrifices by the dealer community -- alongside those of autoworkers, suppliers, creditors and other Chrysler stakeholders -- are necessary for this company and the industry to succeed. … A stronger Chrysler, supported by an efficient and effective dealer network, will provide more stability for current employees and the prospect for future employment growth."
