A friend of mine has 4 citroen relays, and apart from the side doors being a cunt and seizing up on the sliders, they have been ok. The built in so called "smart nav" is absolute dogshit though.
I wouldnt buy one myself as i have never liked the citoen/fiat big vans. But they certainly are no where near as bad as they used to be it would seem.
As long as my mate gets 3 years out of them he will be happy.
