I drove an estate car for years for much the same reasons as yourself Paul. When the time came to change recently i looked around, tried a few estates and then went and bought an Isuzu double cab 4x4. Drives like a car (near enough) decent on fuel and can get kids, dogs, tack, hay, feed, bikes etc in the back easily. Loads more space than an estate and as it's classed as an LGV cheap to run as a company car as well.
