Cheers mate.
Without me even commenting on the ridiculous interest rate of 13.7% that the salesman quoted, he dropped it to 10% to bring the monthly payments down. Again, he did this of his own accord and no prompting.
I was originally planning to do a PCP, but now I don't think its worth it. I will probably put down something like £20K and finance the rest through a high street bank loan. Just as an example, Nationwide's APR is only 6.7%
As a result, Lexus won't be making any money out of me finance wise (unless they match/better the high street bak APR on loans).
I have not discussed discounts etc with the salesman, I'm going to wait until I've had my test drive :)
