I used to have a scenic but I never thought it was a people carrier? It had 3 separate back seats but when it came to actual space in the back and boot my skoda octavia won hands down
At the moment dh has a wee corsa for running back and forward to work in, and it's fine for when he is taking the kids to school/nursery
I have my taxi which is a Peugeot partner, same as a citroen berlingo - massive plus is the back bench seats, totally flat so mega easy for car seats going in and out
Also drive a Nissan qashqai which, while it's very nice, I don't rate it very highly as a decent family car, inside is tiny, and the boot is really lacking
The biggest thing is don't take too much notice of horror stories regarding other peoples experiences with different manufacturers, if you listened to them all, you would never buy a car -all cars have had problems and faults, but there is nothing out there nowadays that is hugely unreliable either
Same with parts availability, most motor factors can have parts to garages next day, if not same day now, unless it's something massively unusual (in which case it wouldn't matter what kind of car it was) it's not usually a problem
When mine needs things done I usually go to the motor factor and pick up the parts myself, saves a wee bit just having to get them fitted
