Which used Volvo XC90 4x4 should I buy?
The older D5 diesel is our pick of the range, although if you're spending more on a later model, the B5 diesel would also be our choice. It provides decent performance coupled with sensible fuel economy. The turbocharged four-cylinder T6 petrol looks a little nonsensical next to the D5, failing to provide vastly superior performance while being far less frugal. It does have better refinement at high revs, but ultimately we’d avoid it.
