i would suggest taking your order with you and checking all the options with it. second: take your time while checking the vehicle. third:walk ouside YOUR car and check the surface and the edges (especially doors), check the gaps (!), then get in the car, and just try everything out (pcm, seat controls(!!!), lights, window controlls....).
while this checklist might sound a bit "anal" it will ensure that you dont have one of those Homer Simpsons "DOH!" moments later....

are you going for a spin in Europe after the delivery?
