Two silver Mercedes collided in Brooklyn last night — killing a man and injuring two teens, authorities said.

The accident occurred at 8:30 p.m. at Avenue I and East Eighth Street in Midwood when one of the luxury cars, which was at a stop sign, inched out of the intersection and the other vehicle slammed into it, cops and witnesses said.

The slow-moving car spun and hit a pole.

“We heard a screech and loud bam,” said Isaac Marcos. “We though somebody hit our garage.”

“Hatzolah [a Jewish volunteer ambulance group] came first and did CPR on him. We heard the horn honking.

“He was hitting the wheel and he wasn’t moving.”

The 34-year-old man died, while two youths in the other vehicle suffered minor injuries.

Cops said no criminality was immediately suspected.
