that way though, do they? Soon enough, the
shopping list escalated exponentially until
he was replacing and upgrading basically
every part of the car, the spec changing
every year as the car was assembled,
disassembled, reassembled again, to the
extent that it received all new bolts and
fixings throughout, fresh paint, and shiny
new parts wherever you may care to look.
“I’ve had a lot of pals help with bits
throughout the years,” he says. “My brotherTwigs, my mate Ben who spent many late
nights with me down the garages, and my
pal Jordan, who was happy to help me cut
the roof off! The car just never at any point
seemed like it would be finished, being
sidelined for other projects and so on; fast-
forward to around 2016 and I decided to get
the management side of things fully sorted
and get the car on the road. It seemed like
that would be the year of the Series One
seeing the road, until a fuel pump gave up
on the dyno. I got a pump ordered without
delay ready for a re-visit to the dyno, but
that’s actually where it sat until 2018.”
