I had my grey 748s repaired on insurance after a slow off, the new prices are shocking and i dont know how easy it si to match the paint finish.
I know the tank is about 850 as ine was replaced under warranty
each side top and bottom is about 600 nose cone about 350 and seat unit mono near 500
I guess ur not fully comp? may be better to paint it another colour. Sorry to be the bearer of expensive news
