Well I did not really buy the car just for the supercharger, I live in Czech Republic and after 6 months of searching I finally found a car which had a good history, low mileage and no crash damage. It happened to have had an apparently wealthy owner who spent alot of money on it hence the supercharger.
As regards the wheels, as I live in Czech Republic it is not viable to sell them through this site, in terms of the retail value I don't know as a quick look at the manufacturers website suggests they only produce to order.
More importantly it is great to get and and drive the car after many years of company diesel estates, to say it is a refreshing change is an understatement.
