Driven Distribution, LLC, a warehouse distributor of automotive aftermarket hard parts, consumables and accessories backed by HCI Equity Partners, announced that it has acquired the auto parts and accessories distribution business of Chicago Parts & Sound. Financial terms of the transaction were not disclosed. This marks the second transaction in the Driven Distribution platform, following the recapitalization of Tri-State Enterprises, Inc. in November 2023.
Based in Elk Grove Village, IL, with additional locations in Illinois and Wisconsin, Chicago Parts & Sound is a warehouse distributor focused on automotive aftermarket parts, batteries, consumables and accessories. The Company serves auto dealerships, independent repair shops, municipalities, governments and company fleets.
Chicago Parts & Sound was founded in 1978 and acquired by Bob and Jackie Lederer in 2002. Since then, CPS has had a tremendous track record of success by providing value-added products and services to its clients, in addition to completing several acquisitions, according to a news release announcing the acquisition. Bob and Jackie said they are reinvesting in the Driven Distribution platform as part of the transaction and will continue to own and operate Police Department Systems (police and emergency vehicle upfitting services) and Coachcraft & Precision Services (specialty auto restoration services).
Bob Lederer, co-owner of CPS, said, “The history of Tri-State Enterprises is in many ways parallel to that of CPS – just in a different part of the country. Opportunities to combine businesses of such similar backgrounds, ideologies, culture, and customer focus make tremendous sense for all stakeholders in each company.”
“We are extremely impressed with the stellar business and established market reputation Bob and Jackie Lederer have built over the past 22 years. The combination of CPS and Tri-State as part of the Driven Distribution platform will enable us to expand our resources and capabilities to better serve our employees and customers,” said Tristan Taylor, CEO of Tri-State.
Scott Gibaratz, partner at HCI, added, “We are thrilled to welcome the CPS team to the Driven Distribution platform. Consistent with our original platform thesis, CPS represents a geographically strategic beachhead in the Midwest and is a great complement to Tri-State’s existing product categories. We look forward to working together to achieve our shared vision for growth.”
Dickinson Wright PLLC served as legal counsel to Driven Distribution and HCI.

These days, many will tell you that the tuneup is dead – a vestige of a bygone era. But I say the answer is far more subjective.
It’s true: People rarely ask for a tuneup. Once the “king” of automotive service, the process of regular adjustments to the carburetor or fuel system – as well as the ignition system – has all but fallen by the wayside. It’s all handled now by a computer. The best part is these computers, known to us as engine or powertrain control modules, do a really great job at it.
The worst part is they do such a good job of adjusting things and keeping cars running seemingly flawlessly that many people overlook the basic maintenance that’s still required. What this means is the tuneup is far from dead. It’s more important than ever, and in many aspects the same as it always was.
The Way it Was
There are many reasons a tuneup was so popular back in the day. Fuel systems (namely carburetors) were inefficient and required occasional adjustment. Spark plugs wore out quickly, often needing cleaning, gap adjustment or replacement. Points wore in pre-electronic ignition systems, requiring a regular dwell adjustment and frequent replacement. Distributor caps, rotors and wires needed frequent replacement to keep ignition systems in top condition.
All of these factors and more contributed to very noticeable drivability issues on older cars, prompting owners to get a tuneup.
Common replacement items also included air and fuel filters, crankcase ventilation filters and positive crankcase ventilation (PCV) valves, not to mention additional services such as a valve adjustment or belt adjustment. So, how does all this stack up to today’s vehicles?
Spark Plugs
There’s no comparison between the plugs of yesterday and today. Modern spark plugs simply work better and last a long time, often as long as 100,000 miles. But here’s the catch: They still wear out. As they wear, the computer continuously adjusts fuel mixture and timing to maintain optimum combustion. The engine runs perfectly the whole time, but behind the scenes, more energy is required to jump the gap of the plug.
This adds additional load to the coils, eventually causing premature coil failure. Then there’s the potential of trouble removing a plug that’s been stuck in the cylinder head for many years. Ignoring spark plugs can be a costly mistake.
It all seems great at first, and plugs definitely don’t need replaced as often as they did in the old days. But, many manufacturers are slimming down the replacement intervals. For me, I’d rather spend a little extra and replace those plugs before the target mileage.
Coils and Boots
Most modern ignition systems are a coil-on-plug system. They generally work or they don’t, meaning replacing them isn’t going to improve performance. But they don’t last forever. If one has gone bad, the others won’t be far behind. And the boots between the coils and plugs? They’re equivalent to a plug wire – just shorter – and they wear out just the same. In most cases, you can’t see them. They’re hidden from view in the middle of the valve cover.
Quite often, the spark-plug-well seals go bad, leaking oil onto the coil boots and destroying them. This is all the more reason for regular inspection, and a reason to replace valve-cover gaskets when replacing plugs, coils and boots. Valve-cover gaskets were never considered part of a tuneup. They can be now.
Tuneups = Maintenance
Air filters are only new for a second before they start to get dirty. Less air to an engine means less performance. The computer again adjusts the fuel mixture to compensate.
Neglected fuel filters can overwork the fuel pump and cause it to fail prematurely.
The mass airflow (MAF) sensor sends critical data to the computer for engine operation. Cleaning them can improve performance and prevent drivability issues.
It’s amazing how dirty throttle bodies get.
Oh, and PCV valves? They’re still on a lot of cars.
Even electric vehicles will require a tuneup of sorts. Battery-management systems (BMS) have an algorithm that can cause the indicated range to be less than it actually is, depending on people’s driving and charging habits. Recalibrating the state of charge will prompt the BMS to recalculate and restore the lost range.
The bottom line: Maintenance. That’s all a tuneup was and what it still is. And maintenance never goes out of style.
