Structural corrosion of sills and subframes
SeriousBodywork & RustDVSA-based analysis records corrosion and structure as the clearest problem area for the Carisma, with 86.5 structural notes per 100 MOT tests and wording such as 'prescribed area excessively corroded significantly reducing structural strength'. Sills, subframes and mounting points rot from the inside out, and corrosion near seat-belt anchorages is an immediate MOT failure. Surface rust is cosmetic; perforated sills or a soft subframe are expensive to weld and can make the car uneconomic. Any Carisma bought without a recent underside inspection is a gamble.
