Rule #1: NEVER take what ANY dealer says at face value!
They are experts in the art of BS, and generally rely on the theory that "if you can't dazzle 'em with brilliance, then baffle 'em with bullsh!t".
"2006 M35x, Sport with Tech" does not accurately describe the car in question. It appears to me to have the U02 navigation system, and the Journey Package only; as it has Homelink and AFS. With the Journey package, it should also have xenon headlights and backup camera.
Tech package would include: 14 speaker Bose (as evidenced by 2 speakers on each front seat), smart cruise control (this car does not have the buttons on the right side of steering wheel for this feature), Lane Departure Warning (this car does not have camera on top driver's side of windshield), among a couple of other features.
As far as being a Cali car, they may be able to claim that since it might have come from auction there, but the history of the carfax tells the real story.
I believe this car here to be with Tech:
http://www.infinitiofkirkland.com/auto/ ... wd/891944/
It has the smart cruise control (compare the steering wheels) and the LDW camera (look at the top of the windshield for a cut out in the solar strip).
And this car to be a Premium:
http://www.beavertoninfiniti.com/Used-2 ... d/16956673
It has everything the above car has, plus rear sunshade and rear control on/off switches in the center console (compare switches to either above car); the overhead RSE, and chrome wheels.
Premiums are a rare find, Techs are more common, and dealers try to confuse the issue. Do your homework, learn to spot the differences, and you will find the car you are looking for!
If I can be of more help, do not hesitate to ask; that's why we are here.
