I have a MKIII and a FL 430. I'm totally sold on the 430. It is sublimely comfortable, yes its not as quiet as the 400 but I think its better, more modern looking and with an LPG conversion you'll be laughing all the way to the bank! It has all the kit that modern cars have now and more and although you can talk to your Ford Fiesta these days there is no way that you could achieve the same levels of luxury that you do in the 430 for the same money. I love my 430 and realy feel the man about town when I'm out in it. I'd avoid the pre-facelift though, it just falls short in kit and reliability stakes from what I've seen, it's also a bit ugly in my opinion. I still enjoy the 400, it's very soft and very quiet but it falls short on kit by a long way.
