2001 Mazda MX-5 1.8L Petrol · RN51 AVL

As a 1.8L petrol model, running costs will be moderate. Fuel economy for this era of MX-5 typically sits around 30-35 mpg, depending on driving style. Tax and insurance groups for a 2001 1840cc model are generally mid-range, making it accessible for enthusiasts but not as cheap as a modern small hatchback.

Maintenance costs can fluctuate; while the engine is generally robust, the MOT history indicates that suspension components and braking hardware require regular attention. Expect to budget for periodic replacement of wear items like tyres, pads, and suspension bushings. An estimated annual running cost is approximately £1,200-£1,500, including fuel, tax, insurance, and routine maintenance.

Focus heavily on the chassis and sills. The 2025 MOT record flagged offside front structure corrosion within 30cm of a mounting, and the 2023 record noted corrosion to the offside rear sill. Use a torch to inspect these specific areas for signs of bubbling paint or fresh welding.

Secondly, inspect the steering and suspension. The 2023 failure involved track rod ends and suspension arm ball joints. Check for any play in the steering or unusual knocks when driving over bumps. Finally, check the braking system; the 2025 advisory noted worn or pitted rear brake discs, so ensure the discs and pads have sufficient life remaining.
