one bluner was going with a dealer selected clear bra installer.... most aren't the best and yet you get charged an arm and leg just to get it.... and another was not doing a close inspectiong before even taking the keys.... another blunder was taking delivery of a car at night in the cold.... learn from these and you'll have a flawless buying experience....although there is no guarantee everything will go smooth 100% of the time... YMMV..
