The original Argyll marque
Alex Govan founded The Hozier Engineering Company in 1899, and it was at this factory that the first Argyll Voiturette was produced; copied from the contemporary Renault, it featured a 2¾ hp de Dion engine and shaft-drive. 1901 models had an upgraded engine of 5 hp; cars made in 1902 were upgraded even further, using 8 hp units. Soon there appeared a 10 hp twin with radiator tubes forming the sides of the hood; in 1904 the company introduced a range of front-radiatored Aster-engined cars. One of these was a 10 hp of 1985 cc; others were fours of 3054 cc, 3686 cc, and 4849 cc. All cars featured Govan's rather awkward gearbox, which had a T-shaped gate and separate reverse and change-speed levers. Argyll had now become Scotland's biggest marque and soon moved from its premises in Bridgeton, Glasgow to a grand terracotta factory in the suburb of Alexandria built for the company by now named Argyll Motors Ltd. This factory was never used to capacity, and the company began to decline after Govan's death in 1907 and, went into liquidation in 1908.
Production restarted in 1910, under a company now named Argyll Ltd., with a new range of cars including the famed "Flying Fifteen", and a six-cylinder model. The 12/14 was widely sold as a taxi even being exported to New York. Four-wheel brakes designed by J.M. Rubury of Argyll and patented on 18 March 1910 by Henri Perrot and John Meredith Rubury (Patent number 6807)  were available from 1911 on, and in 1912 the single Sleeve valve engine designed by company director Baillie P. Burt and J. P. McCollum began production; the entire range featured Burt-McCollum engines by 1914.
Argyll changed hands in 1914 and the Alexandria factory was sold to the Royal Navy for torpedo production. Car production was resumed on a small scale in the original Bridgeton works under the control of John Brimlow who had previously run the repair department. The first product from the new company was a revival of the pre-war 15·9 hp model, now with electric starter but few were sold. In 1922 it was joined by a 1½-litre sleeve valve model and in 1926 by the 12/40 sports.
The company made a final appearance at the London Motor Show in 1927 and the last cars were probably made in 1928 though still advertised until Argyll closed in 1932.
 The second Argyll era
The name was re-used in 1976 by a new company who made a mid-engined sports car, the Argyll GT in Lochgilphead, Scotland.
The new manufacturing company was founded by ex-Mini racer and turbocharger expert Bob Henderson. The new car was named after the original Argyll of 1898, in honour of a grandfather of one of the investors who worked in the Argyll factory at Alexandria.
The only model was the mid-engined Argyll GT (or "Turbo GT"), which was based on a sturdy box section chassis with space frame clothed in a fibreglass bodyshell made next door to the old Arrol-Johnston factory in Dumfries by Solway Marine. The 1976 prototype car featured a turbocharged Rover V8 engine. A version with a turbocharged Saab engine was also mooted, but none was built. The suspension came from the Triumph 2500 and the gearbox was a ZF 5-speed unit. By undoing 10 bolts, the entire rear end, suspension, gearbox and engine came away.
Production versions of the car, which made its début in 1983, had as standard a turbocharged version of the Douvrin Euro V6 as used by Renault, Peugeot and others, together with a Renault 30 transaxle. A turbocharged V8 of 3.5 - 4.2 litres, together with the ZF transmission, was an option, but none were built. Other cars used the Lancia Beta engine and transmission, while a small number featured a Buick V6 which had started out as a stillborn Indycar engine. A top speed of 160 mph (ca. 260 km/h) with the turbo V8 was claimed. Production capacity was stated to be twelve cars a year though Bob Henderson has never stated how many vehicles were actually built. With a quoted price of £25-30,000 at launch (comparable with the contemporary Ferrari 308 GTB), however, numbers were likely to be low. Production ceased around 1990.
