I had a 2004 LX8 Adventra wagon. It was probably one of the best cars I have had. Mine was just stock, unfortunately it got rear ended, so after it was repaired I sold it as it was due for replacement anyway. Very heavy and strong car, but also pretty heavy on juice. Parts are always dearer as lots of parts are cross 8 specific, even things like brake pads. I would go the VZ, I think the interior is a bit nicer, very similar to VZ Monaro and the front and bonnet is a bit newer looking.

However after buying a series two VE, it is so much nicer to drive than the Adventra. If you can try for a low k one, they pop up quite a bit as families are now trading them. I also like the Ochre trim some of the Adventras have.

By the way, if you want something a little rarer, look at the HSV Avalanche. I dont like the body kit, but others probably do.

Cheers Geoff
