When considering a donation to RevUp Richmond, remember that original-paint examples and matching-numbers vehicles command the highest collector interest.

This ensures that your contribution will be recognized as a true collectible, preserving the rich heritage of MG in our community.
📖Generation guide
Mark I • 1962-1967
The original MGB features pull-handle doors, a 3-bearing engine, and a 3-synchro gearbox. Its classic lines and chrome bumpers make it highly sought after by collectors.

Upgraded with a 5-bearing crank, the Mark II introduced all-synchro 4-speed gearboxes and the Salisbury rear axle, enhancing reliability and performance.

Notable for its chrome bumper and recessed grille, the Mark III represents the pinnacle of MGB design, fetching the highest collector premiums today.

These models feature raised ride height and single-Stromberg carburetors, reducing horsepower significantly. They are typically viewed as a discount tier among collectors.

Rare and powerful, this GT variant boasts a 3.5L Rover V8 engine, creating a unique driving experience. The factory grey-market cars are particularly collectable.
Limited Edition • 1980

Known issues by generation
Classic MGBs come with their share of known issues. The B-series 1.8L engine is prone to thrust-washer failure, particularly in early 3-bearing models, necessitating preventive maintenance at clutch jobs. Synchronization of the dual SU carburetors can also be a challenge, requiring regular attention. Additionally, the early models suffer from valve-seat recession due to unleaded fuel, making a hardened-seat conversion a must to protect your investment. While later models transitioned to rubber bumpers and single-carb emissions systems, they often lose performance and collector value relative to their chrome-bumper predecessors.
Donation value by condition + generation
Collector values for the MG MGB Roadster and GT vary significantly based on condition and original features. Chrome-bumper models from 1962 to 1974 typically range from $15,000 to $50,000 for pristine examples, while rubber-bumper models (1975-1980) see a market between $8,000 and $18,000. Original paint and matching-numbers are vital for high collector interest, alongside full disclosure of any rust issues related to the monocoque structure. Factory overdrive variants command further premiums. For accurate appraisal, reference the Hagerty Valuation Tool and auction results from RM Sotheby's and Bring a Trailer, as proper evaluation is critical for donations exceeding the $5,000 threshold.
