When buying used XT4 parts, always match the exact part number and confirm the model year. Parts that look identical between years can differ in mounting points, connectors, or electronic modules. Check condition grades — Grade A (excellent) parts are lightly used with no cosmetic damage, Grade B (good) shows normal wear, and Grade C (fair) may have visible wear or minor damage that does not affect function. Always verify the seller's return policy and ask whether the part was tested before removal.
