MG MGA Twin Cam
The MGA replaced the T-series MGs with a sleek, modern body that looked stunning in 1955 and still looks beautiful today. The Twin Cam version was the performance flagship, featuring a DOHC version of the B-Series engine with Dunlop disc brakes all around — a first for an MG. With 108 horsepower in a car weighing just over 2,100 pounds, the Twin Cam offered genuine sports car performance. However, the engine was temperamental and prone to problems if not properly maintained, which limited its commercial success. Only 2,111 were built before MG discontinued it. Standard MGAs with pushrod engines sold over 100,000 units and are among the most popular British sports cars for restoration. The Twin Cam's rarity and performance make it the most collectible variant.
Twin Cam models with original engines are rare and valuable. Many were converted to pushrod engines — check carefully. Standard 1600 and 1622cc MGAs are the most practical choice. Roadsters are more valuable than coupes. Rust is the eternal MG enemy — check sills, floors, and trunk. Massive parts availability through specialists.
The MGA was produced 1955-1962 with over 101,000 built across all variants. The Twin Cam was available 1958-1960 only, with just 2,111 produced. Many Twin Cam cars had their engines replaced with standard pushrod units. The MGA Mk II (1961-62) increased displacement to 1622cc.
