JCT600 is a car dealership founded in Bradford, England in 1946 by Edward Tordoff - the company is now run by his grandson, John Tordoff.

It has 22 franchises operating from 48 retail outlets across the North of England with an annual turnover in excess of £450 million.

JCT600 takes its name from Jack Tordoff's Mercedes-Benz 600 personalised number plate and it was in a Porsche 911 bearing that very registration that Jack won the International Circuit of Ireland in 1973.
