A forward four post lift is the backbone piece of equipment for any shop running annual state inspections on BMWs, Audis, VWs, and Mercedes, and the used-versus-new decision on one of these units trips up more European-marque specialty shops than almost any other equipment purchase we quote. We’re Auto Lift Services, based in Ames, and we install and service lifts for independent shops all over Iowa, including several specialty European shops around Sioux City that lean on a forward four post lift daily for inspection lane work. The myths around buying used run deep, and we’d rather walk you through the actual math than let a bad used deal cost you a bay for six months.

Myth 1: A used lift is always the cheaper option
The biggest misconception we hear from shop owners is that any used forward four post lift will save money over buying new, full stop. That’s not how the math actually works once you factor in freight, rigging, and the condition of the runways and cables. We’ve quoted plenty of used four-post installs where a shop already owns the unit and just needs it removed from one location and reinstalled at another, and by the time you add a forklift rental, a man lift for the teardown, and travel, the labor bill alone can run close to what a chunk of a new lift costs.
We had a fleet customer south of us that wanted a used unit swapped in to replace an aging platform, and once we priced the removal of the old lift plus the reinstall of the used one, the owner was surprised the labor nearly matched a new-lift quote. A forward four post lift that’s been sitting in a warehouse or pulled out of another shop still needs new cables, a full inspection of the runways for rust or bent decking, and often a hydraulic reseal before it’s safe for daily inspection-lane duty. None of that is free, and none of it is optional if you’re running state inspections where a lift failure means a liability problem, not just an inconvenience.
Myth 2: New lifts take too long to get installed
Shops assume buying new means months of downtime, so they default to used because they think it’s faster. In practice, lead time on a new forward four post lift depends far more on freight scheduling and site readiness than on whether the unit is new or used. We ask every customer the same questions regardless of new or used: is there a pit or is this a surface-mount install, is the concrete rated for the load, and do you have a forklift on site or do we need to bring one. Those questions determine your timeline, not the age of the lift.
One shop we worked with already owned a new four-post unit and just needed the old one hauled out and the new one set, and once we had a date locked in, the whole swap happened in a single scheduled window. Used installs, by contrast, often take longer because you’re troubleshooting an unknown unit on-site, sourcing replacement parts for a model that may be older, and hoping the seller was honest about hours of use. If your Sioux City shop runs inspections five days a week, a predictable new-lift install date is worth more than any per-lift savings from a used unit.
Myth 3: All four-post lifts handle European vehicles the same way
European marque shops have specific needs that a generic used four-post doesn’t always meet. Wheelbase range, runway width for lower European sedans and wagons, and rolling jack compatibility for brake and suspension work all matter more on Audi, BMW, and Mercedes platforms than on a typical domestic truck. A forward four post lift built with the right runway spacing and adjustable jack setup handles a low-clearance European sedan without the tech scraping a splitter or misjudging tire clearance every single inspection.
We’ve walked customers through this before buying a used lift secondhand from another shop that primarily served trucks and SUVs. The runway width was wrong for the low-profile cars coming through the inspection lane, and the shop ended up needing modifications anyway. When you’re inspecting European vehicles daily, matching the lift’s geometry to your actual fleet mix matters more than saving on the sticker price of a used unit that wasn’t built for your work.
Myth 4: Used lifts don’t need a cylinder or cable inspection before buying
This is the myth that costs shops the most in emergency repairs. We get calls constantly for cylinder repair, cable and pulley replacement, and leaky fitting warranty work on four-post lifts that were bought used without a real inspection. One shop’s four-post had a front corner sticking, and once we got into it, it needed the front post adjusted and lubricated, plus new cables and pulleys entirely. Another had a fitting leak that turned into a full cylinder repair job. These are the exact failure points buyers skip when they’re excited about a low used price.
Before you commit to a used forward four post lift, insist on seeing the cylinders, cables, and pulleys in person, or have someone qualified inspect them for you. Uneven lifting, where one side rises faster than the other, is one of the most common complaints we field on used units, and it almost always traces back to worn cables or a sticking post that wasn’t caught before the sale. If you’re running an inspection lane, an uneven lift isn’t just annoying, it’s a safety and liability issue you can’t afford during state inspection cycles.
Myth 5: Warranty coverage doesn’t matter for inspection-lane equipment
Some shop owners treat warranty coverage as an afterthought since a four-post is
