Just purhased a mk4 astra van envoy 1700dti. Catch is, it has a 2.0 DOHC 16v petrol with a pipercross and i don't know what dropd in. Luks real good job, nd it seems to really shift. On the exterior, your talkin standard van at a glance, but 17" alloys and a big exhaust, but under the bonnet is real suprising for a van. Was interested in a meet wi some knowledgeable guys and findin out what sort of thing i am running as ia int gotta clue to be honest. It really seems a rare combination of ugly exterior, practicality but, more enjoyably...power.
