I am no car buff by any means. I buy and sell heavy equipment. So its safe to say I am a Truck guy.One thing about your site that I thought I liked was your ( FAIR, GOOD, AVERAGE DEAL ARROWS BY THE PRICE TAG) Well, WHEN COMPARING APPLES TO APPLES AND Nissan 350 z TOURING ROADSTER TO THE SAME it turns out that this is just a little trick to make people think they are getting a deal when in reality all they are getting one of your sales persons giving the car credits for maybe a newer radio or a new dome light, who knows but your calculator makes no sense except giving the buyer a headache. You almost had me but go look at the Nissan 350 z cars . thanks but no thanks I will go by NADA or Kelley Blue Book.
