As Caterham performance improved, and their kits became more comprehensive,
so their price increased.Currently I believe the cheapest kit is around
9000 pounds, up to around 30000 for a fully finished car. This opened up
the market to competitors - at the momment in England there are around
14 companies selling "sevenesque" kitcars, from Westfield who compete at
a similar level to Caterham, to Formula 27 and similar - who simply sell
you plans for around 100 pounds.
Robin Hood is a unusual company in the Sevens market - most build their cars from tube steel spaceframes - strong, light, but time consuming to build. Richard Stewart - the company's boss - takes the approach of most modern cars. Build the chassis out of folded steel sheet, spot welded and bolted together. This is much less time comsuming to build at the factory, so allowing the cheapest kit with a ready built chassis on the market.
Over the years, Robin Hoods have used a variety of donor cars for engine and suspension - TR7, Triumph Dolomite, Ford Cortina, Vauxhall Chevette and even a 5.8 litre Jaguar V-12. The Exmo uses Ford Sierra components.
The Exmo ("EXport MOdel") was pitched as a minimum cost Robin Hood - the main difference between it and other Robin Hoods is the front suspension - it uses Macpherson struts like many production cars in place of the more usual (for Sevens) double wishbones. The kit sold at 1000 pounds plus tax for a mild steel version, with 80% of buyers spending an extra 350 pounds to upgrade to stainless steel. Optional components - like the roof - were exrta.
The Exmo was sold as a kit on 3 occasions during 1996, each time about 140 people collecting kits from the factory in Nottingham, but production has now moved over to the Mk3 - back to double wishbone front suspension, more complete kit specification, and even an option to fit a Rover V8 engine.
