Not personally in the UK but generally it may be a good idea to consider the following… 
- Inspect Exterior and Interior Condition 
- Request a Full Feature Demonstration 
- Confirm Pre-Chosen Options and Accessories 
- Ensure Infotainment is Fully Updated and Working with Phone 
- Collect and Confirm Warranty & Documentation 
- Test Drive to confirm no issues 
Regarding options, it appears these may be worth considering… 
- Panoramic Sunroof (if not standard) 
- 360 Camera 
- Retractable Tow Bar (if towing of course) 
- Wireless Phone Charging 
- Ceramic Paint Coating 
- Additional Driver Assistance Aids (if desired)
Additional points… 
- Get confirmation of next scheduled service 
- Ask Dealer to demonstrate and help set up features if needed 
- Take your time on pickup day and don’t sign final paperwork until satisfied 
Seems the CX-60 Homura already comes well specced with the most popular features so you probably don’t need to add much more…Hope that helps and please keep us updated with pics if possible!
