UFC Fighter Randy Couture Manager's BMW Explodes

Randy's manager Sam Spira tells TMZ, he was driving to a friend's house several days ago when "without any warning, my BMW X6M burst into flames, exploded and was completely totaled."

Sam says, "I can best describe the event as a very loud bang while going about 10 miles an hour -- there was a speed bump that I slowed down for -- followed by an immediate giant engine malfunction light and flames coming out from the front and under the car."

And if that wasn't scary enough, Sam says his young daughter was in the passenger seat -- and the passenger door wouldn't open. So Sam had to grab his daughter and pull her out the driver's side, burning himself in the process.

Seconds later, Sam says the car exploded and was immediately engulfed in flames. Spira adds, "Had we been traveling on the freeway, we would probably all be dead."

Firefighters arrived to the scene moments later to extinguish the blaze.

To make matters worse, Spira says his BMW dealership has not yet inspected the car to determine why the engine exploded -- and the BMW corporation is ignoring his phone calls. Spira tells us, he plans to sue if the company doesn't do something soon.
