The business, explains ex-Nissan works racing driver and now JD operations manager Chris Ward, turns over £100 million a year and is divided across three divisions – customer car restoration, buying and selling restored classics, and classic car racing. All this is why half the space at JD is occupied by workshops – on site is a body shop, metalworking shop, race workshop, engine shop and a massive store of parts which, we’re told, contains 250 fully-built engines alone. What they can’t do themselves, they entrust to an expert supplier network, mostly based within a two-mile radius.
