I am going to take delivery of my '06 STS tomorrow. Paid $22,800 for a V-6,AWD, Nav, sunroof, wood package,bose 5.1 and heated and cooled seats. White diamond on cashmere. Was driven 27k miles. Is that a decent deal? Just wanted to see what you recommend that I specially look for before I hand them the check. I already drove the car and it seems fine. The paint and interior are in excellent condition. I noticed the AC wasn't really kicking too hard so they are going to fix it but other than that I didn't notice anything wrong with the car. Also how can I tell if the car is equipped with magnaride? This is my first time buying a used car. Thanks for the input!!
