Car number 28 made its début at the 1998 12 Hours of Sebring with Field joined by Butch Brickell and Rick Sutherland but retired after 173 laps.

For ALMS duties, Jon gave his son Clint Field an opportunity to race alongside his father.

Intersport picked up two more victories after Sebring, the first at the Grand Prix of Washington, D.C., and at Petit Le Mans.

In the drivers championship, Jon Field took that crown, 15 points ahead of second place Ben Devlin of Archangel Motorsports.

They did also enter a car in the LMP900 class, racing a Judd-powered Lola B2K/10 chassis for the first half of the season then switching to a Riley & Scott Mk III C with an Élan engine.

The first round at Sebring was a mixed reaction in the team with the LMP675 car finishing second in class in the hands of Jon Field, Dayton and Durand but the LMP900 car of Clint Field, Sutherland and John Macaluso retired but was disqualified anyway for receiving outside assistance while still on the race course.

In October, the team returned to Road Atlanta for the Petit Le Mans which saw the MG-Lola replaced with an all new Lola B01/60.

They won six of the nine events, however the races they did not win, they did not finish at all which cost them the teams championship in the end, losing out to Miracle Motorsports.

Both cars retired at Sebring before father and son, Jon and Clint won the next round in the LMP2 class at Road Atlanta.

The Intersport Lola-AER was very quick at Sebring winning in LMP2 class and finishing second overall, four laps behind Audi's new diesel R10.

They won the following round in Texas after mechanical problems for the leading Penske Porsche forced it to retire.

Intersport won just one race after the Texas round which was at Portland after the leading Porsche retired due to a battery falling off the car from earlier contact between Highcroft Racing and part-time Intersport driver Duncan Dayton.

Interpsport returned to Le Mans in 2006 with Clint Field, Halliday and Dayton piloting the Lola-AER.

Their best class finish was second at the Northeast Grand Prix with Jon and Clint joined by Richard Berry.

For Petit Le Mans, Intersport purchased the ex-Dyson Racing Lola B06/10-AER but this did not help their points drought, retiring at Road Atlanta and in Laguna Seca.

1 Audi failed post-race inspection as the car was under the minimum weight requirement for its class (900 kg).

Due to Intersport being the only other decent full season entry apart from Audi, they comfortably finished second in the teams championship in LMP1.

At the 2010 Petit Le Mans, Intersport was the surprise package as the mechanically troubled Lola-AER completed the race in fifth overall and fourth in LMP1 class but scored the maximum 30 points as it was the highest placed full season LMP1 entry.

For the 2011 American Le Mans Series season, Intersport left the B06/10 and used two Oreca FLM09 LMPC cars.

They won two of the nine rounds during the season, the first being at Mid-Ohio where Kyle Marcelli and Tomy Drissi drove the #37 car across the chequered flag.

The same duo won Intersports second and only win in 2011 at the Baltimore Grand Prix although in the #89 car this time round.
