Have you tried www.drivethedeal.com ? They seem to be able to get good discount but you'll have to wait a few weeks for delivery....

Sadly they are offering £5000 off the list price, which is worrying for those who care about residuals. Why do Lexus supply them at such prices if there is no excess supply??? I am thinkingof buying one, but this is really putting me off. Don't want the Ford problem of endless discounting and lousy residuals.
