when it comes to connects, buy the best you can because you will always kick yourself for not getting the "extra's"
been doing these vans for going on 6 years now and you really don't want the poverty spec ones
there are 3 different power levels, 75 brake, 90 brake and 115 brake and, to be honest, you don't really need to go above the 90 brake ones as they are quick enough
if they have the drivers pack they will come with electric windows and mirrors and hot screens and washer jets
there are also ones with reversing sensors and air con on the options list
57 onwards got the facelifts and went from the 1.5 din round radios to the full double din square radio set up
there were also different seating options so you get no adjustability other than seat back and forth and backrest lean to full lumbar support adjustment and back and forth and rear up/down and front up/down
nearly all have adjustable reach/rake steering but some don't
whatever you go and see, they kill cv joints and tyres, none of our vans have had anything more than 20k out of a set of tyres and some of them go through driveshafts in 20k too
there was a recall on the clutches as the pedals dropped overnight, nothing that pulling the pedal up again won't fix but you can kill clutches in just a few k if you don't find the problem
make sure it's got a full tool kit as well, normally stored behind the drivers seat as this will have the towing eye and jack and stuff which you won't be able to get the spare wheel out of without
some also came with a seperate fob for the remote locking and some are on the key
they don't like petrol though so make sure it's all good
also see if it's got rubber of canvas intercooler pipes as the canvas ones were the recalled ones as the rubber ones split fairly easily
and if the auto tensioner has gone kaput it's an engine out job to replace
at about 100k they may also need steering racks as just lately several of ours have gone down with dodgy racks and it's a 3 week wait to get them replaced
we've had vans from new and one of ours currently has 185k on it and it's still going strong so any questions in particular just ask
