Sounds good from the advertisement - But check everything out.
Enough $$$ work done. Rebuilt - tick, good components used - tick
Special mention of replacing crank shaft - Tick
All paperwork/receipts for work - Tick
Who did the build ?
RWC Fail issues - A-Pillar dials, potentially Billstiens (height & adjustable)
Does the battery in the boot need mod plate. Is it secured properly and vented correctly. Using the Marine box is the first step. So looks like it's all good.
GTR being in Vic I'm not across your RWC requirements and the strictness of your inspection stations.
Having said that it has 17months Rego - TICK
Reason for sale ? would be nice to know. He's spent a fair bit of money for Nil return or enjoyment. (House downpayment (aka missus lulz)
Looks fair condition. But as you already know check it well or get it checked.
If all checks out I think it's good for the price and you can probs knock a grand or 2 off it.....
Any Rust ??
(Don't know it or of it. I'm in Canberra)
EDIT: Is that really OEM FMIC ? I don't think I've ever seen one...
