Rowan Atkinson ran one as a long term test car for EVO magazine in Britain. He liked it well enough as a car, but it suffered all kinds of niggling (and not-so-niggling) faults. He also had the odd distinction of writing his final test reports after the car had ceased production and the company ceased trading. The MG also lost out to the Ford Mustang in a test in the same magazine, although the tester did seem to like the car.
I remember seeing the advertisements in Classic and Sports Car for the auction of the MG and X-power cars. The Bonneville record breaking cars were all offered for sale, as were quite a few prototypes other racing cars, and leftover production cars.
