I have two largish dogs that need transporting for their daily walks and an elderly mother who needs taking to the shops. I have managed with my SEAT Ibiza, which is approaching its third birthday early next year. I only rack up about 8000 miles per year, mainly social domestic. I've loved this little car's performance and economy but I need to change to a four-door with a more capacious boot to accommodate my pooches for longer trips. I don't mind new or secondhand with a good maintenance deal, but I don't have a fortune to spend. Have you got any advice about what car or SUV might best suit my needs?
