As mentioned above, checking the underpinnings and suspension are important with these vans, as they’re quite lightweight machines but often have to do a lot of work. So pay attention to items like bushes, which may have taken a pounding. Turbo failure was quite common on the earlier models, but seems less frequent on later examples like this one. Finally, you’ll look in vain for a manual transmission fluid check plug, although some other versions do have one. If you suspect problems with the oil, it’s a case of draining and refilling.
