If I had to do to it all over again (buy an LS), I would go for the 2nd one - and just remove the dealer pin-striping and black out the side turn signals as soon as it was in my driveway. The previous poster is right, a plastic part is missing from the front of the 1st car and seems a little sketchy.
Start with an offer of $8,500 on the 2nd one and find out if the oil cover gaskets have been replaced. If so, get the paper work on it. That cost of that procedure alone can make up the $8500 to $9700 difference.
