Remember this story the next your grandparents ask for your help cleaning up their house. Somebody found a collection of old cars worth over half a million dollars.

A Reddit user posted the above photo of the 1981 Lamborghini Countach that they found collecting dust in their grandma's garage. The exotic sports car had been parked between a Ferrari 308 and an MG T for years.

Turns out the user's grandfather ran a car rental business back in the late 1980s and had to call it quits once insurance costs got too high. Over two decades later, the cars have been moved from leaky garage to leaky garage and are in pretty poor shape.

If the vehicles were restored to their former glory, they would bring in over $500,000. Here are some more photos from inside the garage:
