Looking at the prices of just 430's and 360's, you get much more of a bargain in the UK ! Do we know why that is, oh I do believe the Euro spec cars are better as well
Generally speaking right hand drive cars are of lesser resale value because its a smaller market. Its always supply and demand.
There’s 70 countries that drive on the left, RHD cars, third of the world. LHD cars in Europe are similar prices to UK. US seem to achieve higher prices for super cars, another factor possibly is US emission control, import tax’s (about to get worse), state tax and local tax.
I believe around 15k 360’s were made and out of that number only 4200 made it to the USA, so they are not that common here like Europe etc.
