First, I would suggest that you take along a "pre-delivery Inspection checklist" when you do your walk through. Flyguy, one of our moderators, has a checklist that you can download from his website. You can access this checklist by going to:

Go through this list when you are there and make sure everything works to your satisfaction BEFORE you drive it away. All lights, all appliances (including h/w tank, furnace, etc) ..... Do a complete and thorough inspection - inside and out. Feel and look in all recesses, cupboards, around the edges for signs of dampness or soft spots.
If something is broken or wobbly - like the table, for example - get the
dealer to fix it to your satisfaction.
