I am trying to locate an old rally car - this was an 1986 Audi 4000 Quattro (charcoal grey/yellow nose) raced in the US by Mike Burke in the 90's, sold in 1998.

Mike has sinced passed away from cancer, but his son is looking to locate and purchase the car if it still exists.  The car was in Michigan last we knew, and we think it may have been sold in Canada.  Please contact me if you might know of this car.  Thanks!
