This was the car the TR7 should have been – it was designed to accept the Rover V8 engine from the outset. Sadly it arrived too late, was in production for less than two years and nearly all were left-hand drive examples for the US market. A handful of UK cars escaped into the wild – many more have since been created on a DIY basis (you can buy a kit from Rimmer Bros). Some price guides carry an entry for these conversions. There are few other differences apart from bigger brakes, radiator and modified crossmember. They might not be original, but are probably the best bet for UK buyers.
