What did I buy to replace it? An '04 reg leon Cupra (non R) with 67k on it for £2995. Already I can feel it's not quite as quick (There's really not much in it and once I remap it I should be topping 200HP) and i can certainly feel the 'dumbing down' of driver involvement over the years as it doesn't handle anything like the '6 but it's far smoother, much quieter and does way better MPG than the '6 could ever wish for. At 70mph it's doing about 1k RPM LESS than the '6 did!
Thanks for all your help over the years!
