You're doing the right thing waiting mate. I was in the same position just a month ago getting frustrated having the cash and the time off work to find the right car with the right spec/mileage/history etc. and doing the daily internet searches!
If I hadn't narrowly missed a mint refex silver one with nigh on every option, I probably wouldn't have been so fussy, as everything changed aspirationally after that! Nearly bought a black one from a dealer which looked great but up on the miles a little (79k). Ridiculously I had the cash and made a close offer (£250 off asking) yet they wouldn't accept and tried to get me to take out finance I didn't need as they get some kind of cashback incentive!!
Hence I'm glad I waited, as a much better private one which had been out of my budget, was suddenly reduced and now I own it. If you buy a lower spec one IMO you end up chasing around for the bits you wanted originally which seems expensive and complicated at times, and/or wishing you hadn't jumped the gun.......................
The xenons are great BTW, as is heated leather, cruise, 18s, sat nav etc etc. - all well worth having.
