CHATTANOOGA, TN (WRCB)  --  For Volkswagen enthusiasts, it doesn't get much better than a Bug-a-Palooza car show that includes hundreds of VW cars.  

"They come from all over; we've had them come as far as Mexico, Canada," says Randy Schneck with Scenic City Volks Folks.

All proceeds from the car show benefit the Ronald McDonald House.

"This past year we actually were able to donate $20,000 to them," Schneck says.

"That helps us bring comfort and care to families of critically ill children," Jules Kinder, with the Ronald McDonald House, says.

The Cofield family knows first hand how the Ronald McDonald House can help.

"Back in October our daughter was kicked in the face by a horse, had a traumatic brain injury," Cofield explains.

They stayed in the Ronald McDonald House for 10 days while their young daughter, Greer, was in and out of surgery.

"Until you live it you don't understand it," says Shannon Cofield. "The Ronald McDonald House was there when we had no place to stay."

Now the Cofields plan to give back to an organization they say helped them a ton.

"For us as a family, the Ronald McDonald House is a part of our family now," Cofield says.

The Ronald McDonald house serves about 600 local families a year.
