I currently drive a Y reg Seat Arosa - bought at a year old ,which has proved reliable and economical for my 1,000 miles per month commuting mainly by motorway. I would like to replace it with a similarly reliable car. I am not attracted to any particular make or model and am not sure whether to keep with a diesel model or move to petrol in these days of increased fuel costs. All I want is a comfortable car that is nippy and economical, ideally with low or no annual road tax payable.
