📖Generation guide

This final chrome-bumper era model features a recessed grille and represents the pinnacle of collector interest, boasting premium values for well-maintained examples.
Rubber-Bumper Era • 1975-1980
Characterized by ride-height increases for US regulations and the introduction of a single-Stromberg carburetor, these models face a discount in collector value despite their practicality.

The final run-out models, often seen as a transitional phase, have unique appeal for collectors interested in the last of the classic MGB lineage.
Known issues by generation
Each MGB generation has its specific set of known issues that prospective donors should be aware of. The B-series 1.8L engine, particularly in the 1962-1964 models, is notorious for thrust-washer failures. Ensuring preventive maintenance, such as thrust-washer replacement during clutch jobs, is critical. Additionally, the SU HS4 twin-carburetors require regular synchronization and dashpot-oil upkeep for optimal performance. The earlier models (1962-1967) feature a positive-ground electrical system, which can complicate electrical service, while 1968 and later models transitioned to negative-ground configurations. Rust issues, especially in the monocoque construction around sills and floors, are prevalent across the MGB lineup, warranting close inspection before donation.
Donation value by condition + generation
The collector value of MGBs varies significantly based on condition and originality. Chrome-bumper models from 1962-1974 typically range from $15,000 to $50,000+ for clean drivers and concours-restored examples, while rubber-bumper models (1975-1980) are valued lower, around $8,000 to $18,000. Original-paint examples and matching-numbers authenticity are paramount for attracting collectors. Variants with factory overdrive can carry a premium of $3,000 to $5,000. Accurate appraisals through sources like Hagerty, BaT, and RM Sotheby's are essential for determining the correct value, especially for those crossing the $5,000 IRS threshold.
Donation process for this model
Donating your MGB requires careful documentation, especially for collector cars. A qualified appraiser is strongly recommended to ensure proper valuation, particularly for original-paint and matching-numbers vehicles. IRS Form 8283 Section B is heavily applicable and should be prepared with precision. If your MG is concours-restored, enclosed transport is advisable to minimize exposure to elements during transport. Documenting chassis condition, heritage registry paperwork, and preventive maintenance records is essential for the donation process.
