The Aston Martin DB2 that competed in the 1949 Le Mans 24-hour race, was stolen in 2002 from Baldock, Hertfordshire and discovered in Holland this year.
Bert Anton Visser, 64, and Heerke Jan Visser, 53, cannot go back to court for sentencing in 2003.
An authorities spokesperson stated the pair were thought to still be in Holland.
Det Sgt Jo Goodson from Hertfordshire Police stated: “We are dealing with the Dutch official to discover them.”
The green prototype automobile was the only one of three Aston Martins in the 1949 race to cross the finish line.
Cops tracked it down to a storage center in Eindhoven in March, but Christopher Angell, the vehicle’s owner at the time of the theft, passed away before it was discovered.
The automobile was ultimately handed to a relative, Ashley Mack, who stated Mr Angell had been left ravaged by the theft of his car.
“Prior to he died in 2003 he was still asking ‘has that good cop got my car yet?'”.
The car had been sold for ₤ 605,000 ($832,000) to an American purchaser at Bonhams’ Goodwood Festival of Speed auction last week.
