Use the actual body and component version, not registration year alone. Compare the listing photographs, reference numbers and any production-date restrictions.
Check the production series and body style, then record the engine and transmission details. Original cars and the 1991 facelift. Compare the fitted component with the product's stated application before ordering.
Compare the complete number, including any suffix, and check the listing's applications, dimensions and mounting details. If the car has been modified, identify the fitted component as well as the original vehicle specification.
Read the individual condition label and description, and review the photographs for storage marks, wear or missing fittings. Check whether the price covers one item, a pair or a set; condition and quantity are product-specific.
