Hey mate,
I've bought my last 2 skylines- both 33, off Joel at Aussie and I would recommend him 100%. Top bloke, both cars were exceptional and mechanically A1. I would however choose the colour you want right from the start theres nothing worse than not being happy with the colour and its a huge pain in the arse to change-just my 2c. Hope that seals the deal for you mate.
Cheers
