I've had several Mondeo estates, which are great, and currently have a Vectra estate, which isn't - load space is fine but the trim on the backs of the rear seats is held on by bits of plastic pushed into channels, which pop out as soon as you load stuff into it. Plus the tailgate switch stopped working just after I'd loaded up for a gig, so had to unload at the venue, load back up, and unload when I got back home through the back doors.
The Vectra's steering pump failed and the garage lent me a Renault Megane estate while they fixed it. What a dreadful thing that was, and only marginally bigger than a Metro. Hated the stupid handbrake on it.
Two members of the ceilidh band I was once in had a Zafira, which was an unreliable piece of crap. Then they got another one, which was an unreliable piece of crap. So I've decided that Zafiras aren't for me.
