G'day KROW - did you used to "love" in New Zealand? It is a really great place - warmer climate in Auckland than Victoria, Canada, where I came from.
The Astras are branded as Holden here and in Australia. Years ago we lived here and owned a 1996 Holden Astra 1.6L petrol - didn't know it as an "MK3" - didn't even know about Vauxhalls. There are also Corsas (called Barinas here) and Vectras etc.
Living here again now and this time own a 1996 Astra diesel. Was the mother-in-law's car - she had it from brand new. We took it over (needed quite some attention) and I think its great. Run it on biodiesel made from used Thai food vege oil.
These forums have been a great help. Learned a lot about diesels I must say. If we ever return to Canada I will try to get my hands on another diesel!
Cheers, Paul
