Injector seal leaks can occur, so check for white smoke on a cold start before buying.
The 1.8 petrol is mechanically simple and very dependable if lower running costs are not essential.
Some early examples show sill and arch corrosion, so inspect these areas on higher-mileage cars.
All petrol engines and the early Toyota-built 2.0 and 2.2 D-4D diesels utilise a timing chain, which is generally maintenance-free. The later BMW-sourced 1.6 and 2.0 diesels introduced from 2015 also use a timing chain, though these require strict adherence to oil change intervals to prevent premature tensioner wear.
The Multidrive S is a CVT paired with petrol models. It is highly robust provided the transmission fluid is replaced every 40,000 miles. During a test drive, ensure acceleration is smooth without juddering or hesitation. Any whining noises under load typically indicate neglected fluid changes or internal bearing wear.
