Known issues by generation
The MG MGB Roadster and GT are known for specific mechanical challenges. The B-series 1.8L inline-4 engine, particularly in the 3-bearing models, is prone to thrust-washer failure, which requires preventive maintenance. Synchronization issues with the dual SU carburetors can also affect performance, and regular dashpot-oil maintenance is essential. The transition from positive-ground Lucas electrical systems in early models to negative-ground in later versions adds complexity. Rust issues in the monocoque structure are common, especially in the sills and floor pans, necessitating careful inspection when considering restoration or donation.
Donation value by condition + generation
The collector value of MG MGB Roadster and GT models varies significantly based on condition and originality. Original-paint examples with matching-numbers can demand premium prices, particularly in the chrome-bumper era, where values range from $15,000 to $50,000 for concours-quality specimens. The rubber-bumper models typically range from $8,000 to $18,000, reflecting their lesser demand. The presence of factory overdrive can add $3,000 to $5,000 in value. For an accurate appraisal, utilizing resources like Hagerty Valuation Tools and auction comparisons is highly recommended, as is disclosure of any rust issues or modifications.
