I think I share all your guys habits. especially taking it easy till she warms up, and i try not to let anyone into traffic that isnt drivng a bimmer or at least a friggin benz. if a hummer h2 wants in ill do everything in my power to not let him in. and i alwas turn around to look at my car when i park it. i even check on it when its in the garage at home. my wife thinks im nuts. but right before bed i check on the car, make sure the doors are locked in the house, then check on my kids. i only check on them last because they are upstairs.
and sometimes after i park ill stick my nose down to the grill and make sure everything smells ok. plus i like the way the car smells when its warm hahaha
