Hi, i sent emails to every dealer within 100 miles explaining what I wanted also what I’d had off previously, most of them replied to say nothing they can do about the a.p as it’s set which is true but I’ve had 500 off the last three I’ve had, admittedly they were high deposits but there’s always someone willing to give you discount, it’s just finding it then hoping it’s not too far away, I found my discount at jct600 mercedes Harrogate which is 45 miles from me which I’m happy to travel to, good luck with your search.
