Though of course the Urvan Estate is much better than the Escapade in many ways being one generation newer, sales were poor compared to the older, cheaper and mechanically simpler Escapade. This means some parts may not be as easily obtained.
The Starex CRDi does not have parts availability issues, but cost may be high for engine-related parts. One advantage of the Starex is the front mounted engine, which makes for a much safer driving position. If you have reservations about parts cost, go for the base turbo intercooler variant.
