Alaska Wheels Forward invites you to donate your MG MGB Roadster or GT, an iconic British sports car that embodies classic motoring. Spanning production from 1962 to 1980, these vehicles have a storied history and a dedicated collector community. Whether you own a chrome-bumper version from the earlier years or a rubber-bumper model from the late 1970s, your donation helps preserve the legacy of these beloved roadsters.
Each generation of the MGB presents unique qualities, from the early pull-handle Mark I to the 1972-1974 chrome-bumper Mark III which commands a premium among collectors. An original-paint, matching-numbers example carries immense significance, while the condition of the monocoque structure warrants attention. We encourage all MGB donors to provide a comprehensive disclosure of their vehicle’s history and condition to facilitate its continued appreciation.
📖Generation guide
Mark I • 1962-1967
The earliest MGBs, featuring a pull-handle door and a 3-bearing engine. These models are highly sought after for their originality and classic features.
Mark II • 1968-1971
Introduced a 5-bearing crank and all-synchro gearbox. This generation offers improved performance and reliability, appealing to collectors and enthusiasts alike.
Mark III • 1972-1974
The final chrome-bumper era MGB, featuring a recessed grille. This generation commands the highest collector premiums for its classic British styling.
Rubber-Bumper • 1975-1980
These models are raised in ride height for safety compliance and have lower horsepower due to emissions regulations. Price factors are significantly lower compared to earlier models.
MGB V8 • 1973-1976
A rare GT-only variant featuring a factory-installed 3.5L Rover V8. Its scarcity and performance make it a higher-tier collector's item.
Known issues by generation
Common issues across MGB generations include cylinder-head valve-seat recession in the B-series 1.8L engine, particularly in early models due to unleaded fuel use. The notorious thrust-washer failure can lead to severe engine damage, especially in the 3-bearing configurations. SU twin-carburetor synchronization is crucial for optimal performance, along with regular dashpot-oil maintenance. While the Mark I features positive-ground Lucas electrical systems, later models transitioned to negative-ground, necessitating care in electrical servicing. Rust issues are significant in the monocoque structure, especially in the sills and floor pans, making thorough inspection and disclosure essential for any potential donor.
Donation value by condition + generation
The collector value for MGBs varies significantly by condition and generation. Original-paint vehicles with matching-numbers are premium-tier, while the chrome-bumper Mark III models typically range from $30,000 to $50,000 for concours-restored examples. Rubber-bumper models, due to their emissions-era modifications, see values ranging between $8,000 and $18,000. As with all classic cars, detailed records of preventive maintenance and disclosures of any frame or rust issues are crucial for valuation. Utilizing resources like the Hagerty Valuation Tool and auction results from RM Sotheby's and Bring a Trailer are essential for appraising these classic vehicles accurately.
Donation process for this model
To donate your MG MGB Roadster or GT, please understand that a qualified appraisal is strongly recommended, especially for vehicles valued over $5,000. IRS Form 8283 Section B is crucial in documenting your donation accurately. Donors should prepare detailed documentation regarding original-paint and matching-numbers status, condition of the chassis, and any restoration history. For concours-restored examples, consider enclosed transportation to protect the vehicle's value during transit.
