2021 BMW 3 Series
At current bid of £4,500, total all-in cost (bid + fees + transport + mid repair) lands around £9,000-£10,500. Post-repair Cat N retail of ~£16,800 leaves a viable margin if repairs stay under £3,000. Recommend not exceeding £5,200. Any drivetrain surprise at the workshop will kill the margin.
