That's the fun part of this business
@Tallcool1; we can all run our stores differently, and measure different KPI's. Through trial and error in my group, I found that not giving key information in certain areas would pop up the lead count, but lower the closing ratio. I also found that undercutting the market too much caused leads to skyrocket, but the customers were only the bargain hunters, and the gross went to shit. If I did a gimmick like CarGuru's and had a price to market tool on the VDP, or "Get EPrice" on my VDP, my gross went in the toilet.
By looking at the big picture and not just being focused on one metric, our group was able to get to 14-15 turns a year in used cars, at 3,500 a copy. Again, no magic bullet, but it was the right cars, merchandised the first day, priced right, and monitored daily for VDP's, leads, demos, working with F&I and the desk to make sure we sold products on the deals, and didn't discount the cars much once the customers arrived, etc.
I also had to realize that the better job we did merchandising the car, the less people would email or call in, and the more they'd just show up. Talk about a pain in the ass for attribution...but show the customer 35+ photos, write a real description, post that if the ad is live the car is still here, etc, and why do they need to contact you? To say hi? Let them drop in, and let the human to human interaction do the rest.
Part of the fun of the car biz is that it's a moving target, and it's an ever changing puzzle on how to move units while making money.
