Thanks for your replies.

After trawling through all the comparison sites and different individual sites the cheapest ive found is Sheilas Wheels for my wife on the BMW 325i Msport and Privilege for the crossfire. Both come in at £1000 so approx £500 each. Which like everyone, im not overly happy with but its is the best by a few hundred quid.

Sainsburys & Tescos were quoting over £1400 for the crossfire alone.

We are both 32, i have 14 years NCB and my wife has 6 years. Live in south london/surrey boarders so I guess i have to live with that.

Thanks again,
