depends on your situation. here is my story:
i also found a car on the lot that ticked about 90% of my boxes, except xenons. i took the car anyway and was happy with it. in fact, it had more options than i wanted and now i would regret not getting the options since i wasn't going to order them. but i still do regret not getting the exact car i wanted. in my case i also needed a new car since my current one was showing its age with brake faults and check engine lights. i would still be waiting for my car had i ordered one.
long story short, order what you want if you can wait or you will regret it.
