Servià moved on to race for the Sigma Autosport (for 2001), Patrick Racing (from the middle of 2002 to the end of 2003, finishing 6th in the championship that year), and Dale Coyne Racing (in 2004, scoring some of the underfunded team's best ever results) teams. Servià also practiced for the 2002 Indianapolis 500 for Walker Racing and Conquest Racing although he failed to get a car into the field.
