A drive for Marcos Racing International in the BPR Global Endurance GT series, saw him finish third in the GT2 class at the end of the season in 1996.

Despite driving in only twelve rounds from a total of twenty-six, he managed to impress many people by challenging with the works team and finishing the season in seventh place in points.

In January 2002 Erdos, together with Ian McKellar Jnr and Bobby Verdon-Roe, ran in the Daytona 24 Hours in a Saleen S7R entered by Graham Nash Motorsport (GNM).

For the 2002 season Erdos was paired with Ian McKellar Jnr in the British GT championship driving the same Saleen S7R run by GNM, now painted white, with support from several AD Group companies together with Mouchel Metro and Renault trucks South West.

In the same year Erdos, together with Pedro Chaves and Gavin Pickering, was entered in the Saleen at Le Mans by GNM.

Erdos competed in the one off 1000 km race run on the Bugatti circuit at Le Mans in November 2003 in an MG EX257 with co-drivers Chris Goodwin and Newton.

For Le Mans he shared the MG with Newton and Nathan Kinch but a good run was ended by engine failure.

A disastrous start with the car overheating on lap 1 and visiting the pits to have the cooling system bled and replenished left them last in class.

However, a remarkable comeback with Hughes and Erdos setting fastest lap times throughout the night resulted in a class win by 4pm on Sunday.

In the Le Mans Series Erdos looked set to win the P2 class, but, in the last round in Turkey, a startline incident involving Jean-Marc Gounon resulted in the MG making heavy contact with the pitwall.

At the final round of the LMS series in Jarama, Spain, Erdos was once again heading for championship victory having dominated the class throughout the season.

Le Mans was less kind to him in 2007 when retirement followed an accident in the Porsche Curves whilst Andy Wallace was driving.
