The difference is £200, which TBH is worth it I reckon, not least because if the ride isn't as nice as you'd like on the Weiteks - you'll always be thinking "Damn, should've got the H&Rs" and you'll probably end up selling the Weiteks on to get them - losing more coins
However you might get the H&Rs, find the ride not to your liking and wonder about the Weiteks - but I think that's a lot less likely. Although you might get the Weiteks and find the ride spot on, in which case, you saved £200! Any chance of a test ride in a car shod with either of them?
