1 PREVIOUS OWNER, 2 KEYS This is a description of the Suzuki Swift SZ3, a petrol-powered car first registered in 2015. It has a 1.2-litre engine and is trimmed to the SZ3 variant. The Swift is Euro 6 compliant and offers a fuel economy of 57 mpg. This is a particularly attractive feature, as it means fewer trips to the petrol station and lower running costs than many similar vehicles.
