What the OP does demonstrate is how limited a lot of saloon cars are. OK for bombing up and down a motorway with a couple of passengers but if you enjoy sports like mtb or windsurfing or kayaking etc they are at best a pain, at worst completely useless. I have a BMW 5 series saloon and a VW T5. If we are going camping, kayaking, windsurfing, mtb, the van is the obvious choice...........yet it serves just as well as most cars for journeys with no load, and most modern vans are just as good to drive as a car. It is permanently loaded with stove/water and coffee makings, bike spares etc, takes 3 bikes easilly and still has seats for 4 passengers and 2 dogs. My van is also used for dumping rubbish, picking up timber/DIY for the house or stables. I can get one bike in the BMW if needed....rear seats folded down, front wheel off and pedal guards fitted but it is a faff!! I also have a removeable tow bar on the BMW and a Thule 2 bike rack..................for emergency situations...e.g. the van is off the road for whatever reason ( except that has never happened yet!)
If I had to reduce to one vehicle, no question it would be the van.............loads more bang for the bucks/Euros/££
