"Thanks for info, I just won with my new car but lost with the wife’s. It’s starting to get expensive." Don't (fully?) understand your comment, unless its US spec car for you and UK spec car for the wife? 2015 car? You bought the yellow UK car that was for sale in April?
no I haven’t bought any more Corvettes this year but my new car has pre 2017 road tax but the wife’s new car a 2018 was dearer to tax than had it of been a 2016 car, non corvette. It’s a minefield.
