The car is priced exactly at KBB retail.
It's definately unusual to get really low mileage like that, but it does happen. I bought "Q2" from a guy who owns his own business and drove it just a few miles from his home garage to his reserved garage space at the office. He spent a lot of time traveling by air, so the car had consistent, but minimal use... Service records are very important in these cases. I felt confident since the records were still in Infiniti's database and this seller was the only owner...
I actually called about this particular Q (mostly out of curiosity) but got an answering machine. If it's the right color (pearl, grey, or green), in excellent condition, garage kept, never wrecked and the price is a little flexible, I might be able to talk my mom into buying it...
