At the end of the season the car was returned to Williams where it remained in storage. In December 2005 chassis 99/03 and 99/04 were due to be auctioned as part of the WilliamsF1 Reserve Collection but the entire collection was brought by an anonymous buyer and the auction cancelled.

In 2007 the car appeared in the Serbian Touring Car Championship

In late 2013 the car was purchased by Simon Garrad and returned to the UK.
