The windows are still boarded up, the car windshields are still smashed in, and the tempers are still boiling over.

One week after the May Day riots left Broadway Auto Row in Oakland an avenue of broken glass and dented metal, the proprietors who are still wondering why they were targeted are still awaiting some help from somebody.

The city held a meeting Thursday and offered vague promises of low-interest loans. But to Erich Horat, the owner of the Precision Motors repair shop, that means he still has to pay for something he didn’t do and something Oakland police didn’t prevent.

“We’re getting the runaround,” Horat said. “What gets me is that the police did nothing to prevent this, and now the city is doing nothing to help.”

Two large glass windows in the front of Horat’s shop at 3068 Broadway remain broken and boarded up. Fixing them will cost $3,000.

Horat conducted a protest of his own. After he boarded up the windows, he painted “Oakland Police, you failed your city again.” He left that up for a few days. On Thursday, he painted over that message and replaced it with “Riot Tourism — Visit Oakland — (Mayor Libby ) Schaaf and (Police Chief Sean) Whent will show you which block to trash.”

Asked who from the city has offered to help, Horat began laughing out loud.

“Ha ha ha!” he said. “I get it. You’re kidding me, right?”

Across the street is the large lot where Premier Hyundai of Oakland stores its new cars. It was there that 66 cars were smashed, dented, tagged or ignited. There they remain, an open sore for passersby to photograph and shake their heads over. Some rubberneckers who dared to stick their heads through the broken window of a torched 2016 Hyundai Elantra Limited (sticker price $23,155) were greeted with an odd combination of new-car smell and burned-car smell.

Dealership general manager Rufus Keller said his insurance adjuster inspected the vehicles on Friday, and the preliminary damage estimate is $200,000. After the cars are repaired, Keller will be legally obliged to tell potential buyers that they are damaged goods, and the cost of the repair “will become part of the negotiation,” he said. Unlike most car dealers, he was not smiling when he pondered negotiating prices.

“It’s going to be a challenge to sell them,” he said. “Even repaired good as new, they have diminished value.”

Still, Keller said, it could have been worse.

“Violence and vandalism are never right, but the police did as much as they could do,” he said. “Nobody was injured and the sun came up the next morning. I would like to see the perpetrators face justice, but I don’t want anyone to go to the electric chair for this.” Keller could perhaps afford to be philosophical because his damage was covered by insurance. Other victims who weren’t covered were angrier.

A couple of doors down, Mike Knowles took a break from a construction job he was working on to stare at the vandals’ handiwork.

“It’s criminal,” he said. “The city needs to support the police, but it’s too afraid of getting sued. So this happens.”

At American Auto Upholstery and Glass, owner Joe Abraham pointed to eight broken front windows and said he just might leave them boarded up. A sign said the shop gives free glass repair estimates, but Abraham said that only applies to auto glass windows, not auto glass repair shop windows.

“I could fix them today, but what about tomorrow? Do I want to come to work every morning wondering if my front windows are going to be there?”

The plywood repair cost him about $200. The plate glass repair would cost more than $10,000.

“This makes my blood pressure go up,” he said. “I can’t sleep sometimes. It’s really ridiculous, but what are you going to do?’’

Like his neighbors on Auto Row, Abraham said all he has gotten from the city is a bunch of apologies.

“Sorry, sorry, sorry, they say. It’s easy to apologize. What good is it? It doesn’t fix my windows.”

Erica Terry Derryck, a spokeswoman for Oakland Mayor Libby Schaaf, said the city was “focused on doing as much as possible” for vandalized merchants. Merchants making emergency repairs to damaged storefronts would not need to buy permits first, she said, and merchants could also apply for grants for “insurance deductibles and out-of-pocket costs” and also apply for low-interest loans.

But the grants are limited and the loan program is “not currently in place,” Derryck said.
