It all depends what you want to do with it, the main differences that are the doors and the seats. Where do you park - will sliders be much better than classic push openers?
Some of the seats are bloomin' heavy to lift and shift and when push comes to shove just not that versatile. We had Galaxys for donkeys years, as you could have the seats in or out to suit job at hand. I could lift and shift the chairs without hubby if required ( some others too bulky or too heavy ) When replaced after a couple of years we re test drove most of them again. Still arrived at the same conclusion.
