I live in the UK and am lucky enough to be considering buying the Volvo XC90 diesel or petrol models. Was in the dealership today and was impressed by the quality of build and interior, we have arranged to test drive the car on Friday. Most importantly the space inside is massive - needed for the family and dog. The car we will drive on Friday is a D5 diesel, there is no T6 petrol demonstrator (although might be a possibility of a short drive in a car they are currently holding in stock). Main concern is the apparent sluggishness (on paper) of the diesel and reviews which suggest its over-taking power is sadly lacking. This pushes me more towards T6 model, which I will have little opportunity to test and manages an average 15 mpg? I know a 2 tonne vehicle is not going to be 'fast', but I would value good in-gear acceleration to overtake traffic on busy roads. The total additional cost to me of the T6 over the D5 is about about another £100 per month - worth it? Would welcome opinions and experiences of either model from owners / drivers. Many thanks Jim
