One owner, low miles, perfect dealer service history, good PPI, good carfax (no wrecks, thefts), hardtop and you like the color and options... sounds like a winner.
Here in LA you can find lots of early S models for a similar price but they have been driven into the ground, have sketchy histories or turned into ghetto sleds with too many cheap bolt ons. As a confirmed 2.5er I don't think you will miss the extra 40 ponies.
