Which used Volvo C70 sports should I buy?
The petrol models are generally cheaper, because many buyers look for a diesel C70 in the belief that they'll save money. This isn't necessarily the case: you'll need to do enough miles a year to justify the extra cost of diesel fuel and the increased purchase price.
The 2.4-litre petrol engine with 170bhp works well, but the 217bhp 2.5-litre version, with 217bhp, feels noticeably faster. The 2.4-litre D5 diesel with 178bhp (available as an auto only until '08) has plenty of low-down pull. In 2007 a 134bhp 2.0-litre diesel was introduced, but it feels a little weedy.
