The Rover SD1 was the replacement for the venerable Rover 'P' series cars and was designed with comfort and style in mind. Initially launched in 1976 with the 3.5 litre V8 engine, this was soon followed up with the 2.3 and 2.6 litre straight six engines, which were based on a modified straight six Triumph engine, converted from pushrod valves to an overhead camshaft system.
The car won many awards in its first years in production, though build quality and reliability issues started to tarnish the range and the reputation of Rover.
A facelifted range was launched in 1982 which also added the 2 liter 4 cylinder 'O' series engine to the range, along with a 2.4 liter diesel engine, new designed 'wrap round' bumpers and a redesigned dashpod for the interior. The overall reliability and reputation of Rover improved over this period, though some issues with the straight six engines remained.
The range was eventually topped off with the Twin Plentum Vitesse (Pictured above), which featured a 4.5 liter V8 engine, Lotus designed air dam and scoops, giving the car a distinctive look compared to the rest of the range. Only a few thousand of these cars were made and are a rare sight today. A twin plentum Vitesse in good condition can command a high price, with good examples of the rest of the range now climbing in value.
A good condition SD1 bought today and looked after is a good investment for the future.
