There's the paperwork and then the vehicle...
Make sure all the #'s are tying-out to what you were led to believe..
Have your sales advisor inspect the vehicle thoroughly before you get there and then you do the same.....Fit, fitment, scratches, wheel condition...Exterior/Interior..
Make sure your sales rep has scheduled enough time for delivery..You (at least) want to ensure you've been taken through basic operations of vehicle and electronics..
Make sure you have all the manuals -- and then READ EM!!
Last but not least -- post pix and enjoy!
