Likely spend is the mid cost of every issue rated common or universal, added together, what an unmaintained example owes over the next few years, not a prediction for any one car. Worst case if everything here failed at once is €2,000, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Body & corrosion

Corrosion at the arches, sills and boot floor6 platform€300–€2,000

Bubbling paint along the rear arches and sills, and scaling or perforation in the boot floor and around the rear suspension mounts. This generation's corrosion protection doesn't match the reputation the make carries, and cars in salted climates suffer early. It's the fault that ends these cars, because the mechanicals usually outlast the body.

Check: Put it on a ramp and look at the arches, the sills and the boot floor in good light before you look at anything else. Walk away from perforation rather than negotiating on it.

How to read this

Every issue is authored once against the part that actually carries it: the engine, the gearbox, the chassis or a shared component, and inherited by every variant that has that part. The badge next to each issue says where it comes from, so you can tell an MZR20 problem from an E9x problem.

Evidence tiers. Manufacturer means a recall, technical bulletin or revised part number. Documented means workshop data or multiple independent sources. Reported means owner consensus with no hard confirmation, and never sets a risk level on its own.
