Known issues by generation
Each MGB generation presents its own set of known issues. The B-series 1.8L engine is particularly prone to thrust-washer failure, especially in the 1962-1964 models, necessitating preventive maintenance during clutch jobs. Synchronization of the SU HS4 twin-carburetors can be tedious, requiring regular attention and dashpot-oil maintenance. Additionally, the Lucas electrical system’s polarity varies between early positive-ground (1962-1967) and later negative-ground (1968+). Pay special attention to rust issues in the monocoque sills and floor pans, which are common concerns for all models, as they can significantly impact resale value and safety.
Donation value by condition + generation
The collector market for MGB Roadsters and GTs demonstrates clear value patterns. Chrome-bumper models (1962-1974) start at $15,000 for clean drivers, reaching upwards of $50,000 for concours-level restorations. Rubber-bumper vehicles from 1975-1980 typically range from $8,000 to $18,000, reflecting their lower desirability among collectors. Matching-numbers status and original paint are critical for evaluation, with factory overdrive variants enjoying a premium. Proper disclosure of rust issues is mandatory, especially for sills and floors, making thorough inspections essential for a valid appraisal. Resources like Hagerty and BaT are invaluable for establishing a fair market value.
Donation process for this model

Documenting original paint, matching numbers, and any historical maintenance records will enhance your donation's value. For concours-restored examples, enclosed transport is recommended to maintain their pristine condition.
