Pricing looks reasonable. $5K to $6K less than the other one here for a year older but roughly the same Ks. Certified by Kia. Good.
A couple of tricks you can try to get some more off the price.
Always buy at end of month. You are right at that point. Sales figures run monthly. More expensive start of month. Cheaper end of month for two reasons. 1. They made their budget and the rest is icing. 2. They didn't make budget and need the sale. Usually got to PAY by end of month not order as they need the cash for the books.
Get there two hours before close. No earlier. Waste time. Look over and over the vehicle. Can't decide. Go across the road for a coffee to think about it. Waste time over there. Make sure they have your number to call you....This often gets them worried you will go home from there. As it gets closer to closing time the dealer will be getting more anxious. They could "lose" you if they don't make a move. Wander back if they haven't called you. Say you are "nearly" there but you really need to be at $28,500. Be prepared to walk, say look, I can't afford it, $28.500 I'm tapped out. If they let you walk and you still want it ,come back tomorrow.....let's see if they come at a final price before you leave. It's closing time.......
