📖Generation guide
Mark I • 1962-1967
The original MGB with pull-handle doors, 3-bearing engine, and 3-synchro gearbox. This version is highly sought after due to its rarity and classic charm.
Mark II • 1968-1971
Upgraded with a 5-bearing crank and all-synchro 4-speed gearbox, this variant offers enhanced performance and is a favorite among collectors.
Mark III • 1972-1974
Featuring a chrome-bumper and recessed grille, this generation commands the highest collector premium among MGBs, ideal for enthusiasts seeking quality.
Rubber-Bumper Era • 1975-1980
These models feature raised ride height and a single-Stromberg-carburetor setup, resulting in lower performance but a more affordable entry into the MGB collector market.
MGB GT • 1962-1980
The GT variant offers a practical hatchback design while maintaining the iconic roadster appeal. Although it typically fetches less than the Roadster, it's a desirable addition to any collection.
Known issues by generation
Each generation of the MG MGB has its unique set of issues. The B-series 1.8L engine is prone to thrust-washer failures, especially in early 3-bearing models from 1962-1964, necessitating preventive maintenance. Synchronization and maintenance of the SU twin-carburetors are essential for optimal performance. The electric systems differ significantly between the positive-ground early models and the negative-ground versions from 1968 onward, requiring careful attention during service. The rubber-bumper models from 1975-1980 also face performance challenges with emissions restrictions, resulting in a power drop from 95hp to just 65hp. Collectors need to be wary of monocoque rust in sills and floor pans, as well as wear in wire-wheel splined hubs.
Donation value by condition + generation
The MGB collector market is robust, with chrome-bumper models from 1962-1974 typically valued between $15,000 to $50,000, depending on condition and originality. Original-paint examples with matching-numbers are particularly prized. Rubber-bumper models, while generally less desirable, can still range from $8,000 to $18,000 for clean drivers. Collector-grade examples, especially those with factory overdrive, can fetch premiums of $3,000 to $5,000. Accurate appraisals using tools like Hagerty Valuation or auction comps from RM Sotheby's are essential for establishing value and ensuring a fair donation process.
Donation process for this model
Donating an MG MGB Roadster or GT involves several key steps. We highly recommend obtaining an appraisal from a qualified expert to establish its market value, particularly if the vehicle is expected to exceed $5,000, as IRS Form 8283 Section B will be heavily applicable. Proper documentation of original paint, matching numbers, and any noted condition issues is essential to maximize your tax deduction. For concours-restored examples, enclosed transport is recommended to maintain the vehicle’s pristine condition during transfer.
