That’s the problem now with buying goods in the US, the terrible exchange rate, especially if your doing the deal by bank/credit card, as the rate is even worse.
Import charges, VAT etc is the same for everyone, private individuals or businesses. Plenty of shipping options out there.
The big boys of corvette parts supply, ie Ecklers, Corvette Central, Zip, Paragon etc all often have specials on interior parts so worth keeping an eye on them. Sometimes as much as 20-25 %.
Buy wisely for a great deal.
Good hunting.
