Awesome looking car! Your first concern should be, CAN you get it through a blue slip as is? If not, how much will you have to change and spend to get it through?
When making a purchase like this make sure you have cash spare for these sort of issues!
The car looks really well built BUT NSW rules of late have been so strict and are being enforced, so if there are any potential defects on the car in NSW then work out what to do about it before it happens...
I would say the car may be known by the SAU VIC guys, try ask them?
But REVS check, EPA check and speak to a Blue Slip station!
