Investing £150 to £300 in targeted preparation yields £600 to £1,500 higher offers. The highest ROI actions are: (1) Fresh 12-Month MOT (+£400–£600 value vs an MOT expiring soon), (2) Professional deep valet & upholstery shampoo (+£300 perceived value for £80 outlay), (3) Alloy wheel refurbishment (clearing kerb rash for £50/wheel), (4) Paintless Dent Repair (PDR) for shopping trolley dings, and (5) High-resolution, well-lit photography with a clear 360 view.
First impressions dictate how aggressively buyers will attempt to negotiate down your price. Simple, cost-effective prep work removes buyer bargaining chips before they even arrive for a viewing.
