2009 British Touring Car champion Colin Turkington claimed his first victory since his return in race three at Donington, the first for the new eBay Motors BMW.
Gordon Shedden was on the podium again just ahead of Matt Neal after the pair muscled past the MG of Sam Tordoff on the final lap.
Turkington jumped poleman Tom Onslow-Cole‘s Team Hard Volkswagen CC at the start and despite his soft tyres going off at the end had built up a substantial enough lead.
Onslow-Cole held second early on, one of the few harder compound-shod cars, but Aron Smith and Tordoff soon made it by, Tordoff then taking second on lap four before struggling with tyre wear.
Shedden was up to third with four laps still to go, passing his team-mate when Neal was behind Onslow-Cole before dispatching Smith and Adam Morgan.
The Scot caught Tordoff on the final lap and with Neal now behind him as well, the MG ran wide at McLeans, allowing the Civics through.
Tordoff did manage to hold off Morgan for fourth, while Onslow-Cole was an impressive sixth in the still-young Volkswagen.
Jason Plato was a disappointing 8th, but extended his championship lead to five points from Andrew Jordan, who was only 13th after he pit to clear grass from the front of his car. Shedden is now 20 points behind the lead MG in fifth.
Joe Girling took the Jack Sears Trophy, the only S2000 finisher in his Chevrolet Cruze.
