Sweet.
Depends where you want to be during which period of time. The Southern Festival of Speed takes place over 4 tracks from Ruapuna in CHCH, Levels in Timaru, Street Circuit in Dunedin (might not be on the calender just yet again this year) and at Teretonga in Invercargill.
Usually some epic cars to be seen at such events.
The meet Rob is talking about is getting bigger and bigger every year, there's also the 4 and Rotary Nationals, that would be hilarious for someone from the UK to see the generic modification stamp on those vehicles.
Plenty to see. I'll try get you some dates for the FOS and the other events I mentioned and you can try figure out what you want to do or where you want to be, from there.
Also. 260Z. Rob.
I don't think either of my Skylines will be ready by then but when you're down in Invercargill you're welcome to come say hello and check out the C110 in the garage and I can take you out to where the Prince sits, if you're interested.
Which reminds me. Wreckers yards. You'll probably come across a good few. Preston St in Invercargill is a good one, unfortunately unable to wander around it freely, but there's also the world famous Horopito Wreckers, also known as "Smash Palace"

Magic.
You'll have a blast.
