Just had my corners swapped at the weekend by KWIK-FIT of all people - Continental SportContact3 - these are usually £179 each plus fitting

from Kwik-fit and not that much cheaper on the internet. However, I got a deal for 4 fitted at my house (an absolute pleasure) for £485 all-in. I had Eagles before and these lasted 32K miles which is pretty good, but I must admit the Continentals are in a different league, so quiet and they don't track every bump and line on the road - ofcourse it comes at a cost but I'm a firm believer in you get what you pay for - so just haggle as if your life depends on it.
