Thinking of going back to Volvo for our replacement towcar with a second hand V70. Our old 740 was very reliable and went on for ever but it was only 2ltr and was hopeless as a tow car. Is the V70 any good for towing and is it as durable as the old 740? Also is it really best to choose the diesel engine? If not the Volvo, any other recommendations for a good sized estate to replace our Vectra SRI150. Thanks, Jim.
