Sorry just seen your post, been out at the Adelaide Show ALL day!!!
Give yourselves time, it is a horrible feeling but you will get there.
We ended up buying a car off a post on here but looked at loads on South Road, but they are all closed on Sundays.
We got car insurance from Aami....very competetive and could do it over phone or online.
We aren't far from you, we are in Seacliff so if you fancy a drink or a cuppa then give us a call....will PM you our number.
Take time to get over the jet lag.......couldnt believe how long that took. Anyway here if you need us!
