Thats why I traded mine in for a vec vxr, for the doors , 300bhp & 400lb/ft ... And it was cheaper than a cupra !! (Until you look at running costs), and it was bigger than a cupra too = better ??
extras ?? You get 1/2 leather in the vxr for a start, you could find a hundred things eachj have & don`t , depends what you are looking for ... (And it had a centre exit zorst before your K1 *lol*)
I am not a K1 fan myself, but the Vectra VXR is not exactly an aficionado's first choice now is it? It does not have 300bhp and 400ft-lb out the packet either - nor does it do 170mph standard.
Think Mr Clarkson sums up the Vectra VXR quite well in this little clip....

Hardly surprising a car with poor mpg, high emissions, severe depreciation and crap looks/handling is cheaper than a Cupra. Oh, and before the performance figures and top speed are thrown in to the hat, remember that the Vectra VXR outweighs both the Astra VXR and Leon Cupra TFSi by 800cc, 2 cylinders and a slightly different turbo set up (not to mention about 1/4 of a tonne lol).
