Which used Mazda 6 saloon should I buy?
Petrol power comes in the form of a 118bhp 1.8-litre, or a more capable 145bhp 2.0-litre that's almost as fuel efficient. There is a 2.5-litre petrol engine, but it's rare and not really worth the time you'll take to find it.
This version of the 6 was originally available with a 138bhp 2.0-litre diesel engine, which was punchy, but a bit raucous. You're better off looking for the 2.2-litre unit introduced in early '09, with either: 123bhp, 161bhp or 182bhp. We'd opt for the 161bhp version because it delivers a useful blend of performance and efficiency.
