Which used Hyundai Tucson 4x4 should I buy?
As on most 4x4s, the diesel engine makes the best choice, of course. Naturally, it's the lightest on fuel, but the extra pull low down in the rev range means it's ideal for off-roading and towing.
The 2.0-litre petrol is worth looking at, though, especially as its 34mpg is not far short of the diesel's. It's also the only engine available with two- as well as four-wheel drive.
