Don´t know about UK market but here in Sweden there are no 2003/4 Caravelles!
First years they only sold the lower spec Shuttle as a people carrier here. I think the first year of the Caravelle was 2005.
Bought my 04 Caravelle for 11,250 from a VW dealer (Heron in Newark) last October had 86,000 miles on it. They are out there if you keep on looking. Try contacting them as one of thier customers has a load of blue ones which they change at 4 yr old.A:
