Hi and welcome to the forum - what an excellent choice!
All Coupes are 3.0 Si models, but there are SE and Sport versions. I could live with an SE, but not with the standard seats that BMW call "Sport" seats - Sport models have "M-Sport" seats which are so much better that used ones can sell for £700 to £800!
You might be surprised at some of the features that are options (cruise control, rear parking sensors, controls for the stereo on the steering wheel, etc.) so work out what ones are "must-haves" and which are just "would likes".
And it may be your lucky day - this one is for sale on here and is in one of your chosen colours:-

It's got all the extras except electric folding mirrors - if I didn't have one already I'd be all over it!
I know it isn't near you, but bear in mind less than 2,500 3 litre Coupes came to the UK and that some are automatics so you'd be very lucky to find one local!
Anyway good luck with the search, and humour us with a photo or two once you've found one!
