MG Rover Rover 45 / MG ZS
The Rover 45 and MG ZS were based on the aging Honda Domani platform, heavily facelifted to fit the Rover family look. While the Rover 45 was marketed as a comfortable, traditional premium hatchback or saloon, the MG ZS was completely re-engineered by MG Rover into a surprisingly capable, sharp-handling driver's car, particularly in the V6-powered ZS 180 guise. In the UK, they are now rare sights, suffering from steep depreciation and scrappage schemes. Reliability issues center around the K-Series engine's notorious head gasket, though the Honda-derived underpinnings are robust. The ZS 180 remains a fantastic, cheap track-day or B-road car for those willing to maintain it.

VIS Motor Failure (V6)
medium severityVariable intake motors fail, leading to reduced performance.
K-Series Head Gasket Failure (1.4/1.6/1.8)
high severityThe K-Series petrol engines are prone to head gasket failure due to plastic dowels and low coolant capacity. The 2.0 V6 also uses K-Series architecture and shares similar cooling weaknesses.
Water Ingress (Bulkhead Seam Failure)
