The Caterham 7 WAS the Lotus 7, when Lotus were axeing the car Caterham bought the rights to it and carried on production eventually making subtle changes of their own.jreay21I thought there was something going on, wasn't the caterham super seven based on the lotus 7? It seemed a bit odd, as caterham and lotus were sort of rival companies, then again, this is a regular occurance in the motor world, peugeout and citroen, for example.
