I was looking around at these van/car type things too and eventually settled on a Fiat Multipla. Works well for use as we’re a family of 3 which means the back seats can be taken out leaving a huge space in the back. They’re actually quite short, so parking is simple (helped by the huge windows). I can get a couple of bikes in the back with wheels on, but removing just one wheel means I can carry 3 bikes plus loads of camping gear etc. very easily.
The Doblo we test drove felt like a bag of bolts.
The older Partner/Berlingos were pretty nice. Some of the models had lots of cubby spaces, handling was pretty neutral. Some of the interior finishes were a bit suspect and showed wear easily (this may not matter to you). Nice engines in the TDs too.
Check out speed limits for van-derived vehicles too. There was a thread on here recently where folk were surprised that the limits were lower than for cars.
