This Homebuilt Evo powered buggy started life with Rhys O’Brien back in 2013. Orignally competing in C Class, the ‘Slack Performance’ special would narrowly miss out on 1st in C Class for Northern Zone multiple times taking out 2nd & 3rd. Its highest result to date was 9th overall at Counties in 2016.
The buggy was sold and ended up in the hands of Sean Cushing, who converted it to J Class specifications. After some initial teething issues at the Two-Day-Trial in 2020, Sean & new navi Geoff Butcher would go on to equalise J Class honours with Hayden McGill in 2021 and win J Class outright for 2022!
The offseason saw them lengthen the Dirty Evo bringing it up to date with the times, however health issues in the 2023 season saw them only take part in two events.
