OK, I’m going to go out on a limb to challenge a conventional notion. I’m really troubled by the concept of “core inventory”. I’m not saying that each store doesn’t have a certain natural traffic profile based on its brand, location and community, but I am suggesting that the notion of a “core inventory,” while appealing and comforting, is fool’s gold.
The idea of “core inventory” suggests that there is a fixed profile of used vehicle inventory that produces optimal results. In other words, if you stock certain types of vehicles, you’ll be well on your way to success. This notion makes the assumption that the automobile market place is steady and predictable. Without the assumption of steadiness and predictability, one could not legitimately suggest that dealers should stick to a defined core of inventory mix.
However, the truth is that the used car market place, by definition, is anything but steady and, in fact, is extremely unpredictable. There are hundreds of factors that are at play in our environment that influence consumer’s purchase preferences and they are anything but steady and predictable. Fluctuating gas prices, interest rates and weather patterns are just a few causes that constantly befuddle those that attempt to stock inventory today based on what has worked in the past. In fact, the ultimate irony is that dealers who purchase such solutions for the purpose of maintaining “core inventory” are usually doing so because they’re dissatisfied with their own past performance. It seems insane to keep doing the same things and expect different results.
As uncomfortable as it is, we need to let go of our security blanket or in the words of Thomas Friedman, our “olive tree” and accept the fact that in the words of Bob Dylan, “time are a changing.” We must embrace uncertainty and accept the fact that what worked last year, last quarter or last month may not work today. This means that we must keep our finger on the pulse of the market place and take our cues from it in “real time” rather than from history. Our present inventory must always reflect the market at the moment. If gas prices are up, way up, we have to dump gas guzzlers in favor of compacts. If we’re experiencing unusual amounts of snowfall, we must quickly respond with more 4-wheel drives. If silver cars loose their appeal, we must quickly respond by changing our preference of color choices. We simply can no longer afford the convenient comforting thought that what worked in the past will work today or tomorrow. The only things that are constant and predictable are death, taxes and change. Let’s wake up, smell the coffee and realize that the notion of “core” is rotten.

Changes in interest rates, fuel costs are all “complements” to vehicle sales. We all know how these can affect sales, but I will also say that “substitutes” can affect sales as well. Let’s say you’re stocking Chevy Tahoes, and then a huge influx of Ford Expeditions enters the market and increases the days supply which ultimately lowers the transaction price for Expeditions. Your sales of Tahoes will fall, because the lower price of Expeditions will cause some of your buyers to switch over. This is cross-price elasticity. Basic economics 101.
Amen brothers! Ever heard the phrase “Past performance is no indication of future results”? Inventory requires some forward thinking. The best way to get in real trouble with your pre-owned inventory is to rely moslt on past performance.
I do think when it comes to factory certified late model vehicle core makes sense. If I have a late model Ford Focus and can not certify it and the Ford dealer has a late model Cobalt which I could certify and he could not, we’d both be better off swapping. Same goes for Hondas and the others. Once the years and mileage get beyond the Certified vehicles I believe the argument against core makes more sense. In fact it would be nice to capture sales data from the dealer’s DMS and display a dealers past performance on a similar vehicle when he’s using live pricing if he has actually sold a vehicle similar to the one being currently priced
In my previous job, when I consulted on the statistical modeling of inventory plans for a large used car retailer, we referred to the notion of a “core inventory” as “driving with the rear-view mirror.” These old guys who go to auction and buy based on “gut instinct and experience” could survive when everyone else was doing the same thing. Now that we have access to real market data, the old ways will get you in deep trouble.
