When you drive to a party and wind up having a big night, it's best to leave your car there overnight.

But heroic Richmond star Dustin Martin has taken this sensible approach to the next level — his car has been at the MCG since the AFL grand final.

Dusty appears to have had so much fun since his team's premiership win, nearly two weeks ago, that he hasn't gotten around to picking it up.

But those at the MCG aren't too fussed, saying the car is safe in the underground car park.

"I can confirm Dustin Martin’s car has been in the MCG’s secure underground car park since AFL grand final day," MCG spokeswoman Sophie Henderson said.

"In the busyness between AFL grand final day and going overseas, Dustin didn’t get the chance to pick the car up.

"The MCG has been happy to accommodate the car’s storage until Dustin returns from overseas."

Martin appeared a little worse for wear for the Tigers' family day at Punt Road Oval the day after the grand final.

Asked how his night panned out, Martin replied: "I don't remember."

The superstar's car is still parked in the bowels of the MCG and it will be for some time.

He is now on an overseas holiday and multiple reports suggest Martin, Richmond and the Melbourne Cricket Club are more than happy to let his car sit until he returns.

Martin rated the 2019 flag as a greater achievement than his first premiership in 2017.

"Both are very special but this is probably a bit better because we can soak it in a bit more," he said the day after.

"It's awesome, I can't believe it, it's so surreal. Two premierships - I'm so proud of the whole club and all of the fans."
