John Arnold Clark was born in a tenement in Townhead, Glasgow on 27 November 1927. His Father was a Clydeside shipworker. He attended Dennistoun primary school, and went on to Our Lady's High School, Cumbernauld, then left home aged 14 with no qualifications. During the war he moved to Arran.
Clark left the RAF in the early 1950s, but was unable to find employment. He used his demob money to purchase a 1933 Morris Ten-Four for £70, and after restoring it, sold it for a profit. Clark started buying and selling cars, opening his first showroom in 1954 in Glasgow's Park Road. He secured his first Retail franchise for Morris Motors in 1959, then during the early 1960s established showrooms in Bothwell Street and also in Paisley and Bearsden.
He launched a Finance company in 1963, meaning people no longer needed to involve their bank manager when purchasing vehicles from him. In the 1960s, Clark also expanded into the rental vehicle market. In 1968, took over Grant, Mel Rose and Tennant giving the company an accident repair centre. By the late 1980s, Arnold Clark had branches across Central Scotland and one in England.
Clark bought the Maxi yacht Drum in 1988. The 78 foot craft is sailed with a crew of 22. That year, Clark led the annual Tobermory race, before Drum was involved in a collision with a Royal Navy submarine, around five miles off the Mull of Kintyre. He loaned it back to Simon Le Bon in 2005 and the yacht was often loaned to other organisations to raise money for charitable work.
By September 2002, Arnold Clark had 97 dealerships and with annual sales expected to reach £1 billion, it was considered Scotland's largest private company. In May 2006, the company acquired the Harry Fairbairn BMW and Mini dealership. The company opened a car showroom in the regenerated Glasgow Harbour, which at the time was Europe's largest. The following year Clark's company was approaching a £2 billion turnover.
In the 2004 New Year Honours, Clark was created a Knight Bachelor, for services to the motor industry, and for his community work in Scotland. The University of Glasgow bestowed an honorary degree upon him in 2005. He was presented with Car Dealer Magazine's Lifetime Achievement Award in 2015.

In September 2014, the company’s turnover reached almost £3 billion.
