About the MG MGB GT
The MGB GT was introduced in 1965 as a fixed-head coupé variant of the popular MGB roadster. Designed by Pininfarina, it featured a distinctive glass hatchback and occasional rear seats, offering greater practicality than its open-top sibling. The majority were powered by the reliable 1.8-litre four-cylinder engine producing around 95bhp, though V8 versions arrived in 1973 with a Rover 3.5-litre V8 producing 137bhp.
Production continued until 1980, with chrome-bumper models (1965-1974) generally more sought-after than rubber-bumper versions (1974-1980). The MGB GT V8 is particularly rare and commands premium prices. These classic GTs are valued for their timeless design, mechanical simplicity and strong enthusiast support, with excellent parts availability through specialist suppliers.
What Affects the Price of a Used MG MGB GT
Condition is paramount with classic cars - originality, restoration quality and history documentation significantly impact values. Chrome-bumper models typically command £2,000-£5,000 more than equivalent rubber-bumper cars. MGB GT V8 variants are the most valuable, often fetching £25,000-£40,000 for good examples.
Bodywork condition is critical as MGBs are prone to rust in sills, floorpans, wheelarches and the rear subframe mounting points. A car requiring extensive restoration may be worth half that of a solid example. Matching numbers, original colour schemes and comprehensive service history all add value. Mileage is less crucial than condition, though very low-mileage original cars attract premiums. Recent professional restoration, overdrive gearbox and wire wheels are desirable features that increase prices.
Tips for Buying a Used MG MGB GT
Inspect thoroughly for rust, particularly in structural areas including sills, floorpans, chassis rails and rear spring hangers - use a magnet to detect filler. Check the condition of door bottoms, wings and the area around the windscreen frame. Verify the engine number matches the chassis plate to ensure originality.
Test drive to assess gearbox smoothness, clutch operation and steering feel - worn components are cheap to replace but indicate overall condition. Check for oil leaks from the rear crankshaft seal and smoke on startup. Join an MG owners club for buyer guides and consider having a pre-purchase inspection by a marque specialist. Budget for ongoing maintenance as these are 40-60 year old cars. Verify the car has an age-related MOT exemption or current MOT, and ensure it's registered with the DVLA correctly.
