A pre-owned sedan arrives on our lot with a history. The inspection is how we read it. Before a car is offered for sale at Genesis of Norman, it moves through a multi-point review that treats the vehicle the way the engineers treated it on day one — with attention paid to the details most buyers will never ask about.
What follows is a plain-language walk through that process, section by section, so you know what has already been accounted for before you sit down behind the wheel.
The exterior and body walk
Every inspection begins the way you would begin one yourself — slowly, standing back, then closer. A technician works the perimeter of the car in daylight, checking panel gaps, paint consistency, and the alignment of the Two Lines along the body for any evidence of prior repair. Trim pieces are tested by hand. Badging is confirmed. Glass is examined for stone chips and for the fine stress cracks that can hide at the edge of a windshield.
Wheels come off. Each is inspected for curb rash, true, and correct torque on reinstall. Tires are measured for tread depth across the face, not just in the center, because uneven wear tells a story about alignment and suspension that a single reading would miss. Oklahoma is hard on paint and harder on glass — hail, sun, red dust on county roads — and the body walk is where any of that would be caught. If you want the longer version of how we think about storm damage specifically, our notes on hail repair in Oklahoma go into more depth.
Under the hood
The engine bay is inspected cold, then warm. Cold, the technician looks for seepage at the valve cover, oil pan, timing cover, and power steering lines. Fluid levels and condition are recorded for engine oil, coolant, brake fluid, transmission fluid where applicable, differential fluid, and washer fluid. Hoses are squeezed for softening and checked at the clamps. The serpentine belt is examined for glazing, cracking, and correct tension — the kind of look we describe in our serpentine belt timing write-up.
Warm, the technician listens. A cold start has its own vocabulary; a warm idle has another. Both get documented. The battery is load-tested rather than only voltage-checked, because a battery that reads fine at rest can still fail under demand. On all-wheel-drive sedans, the differential fluid is pulled and judged by color and feel, a point we cover in our differential fluid intervals piece.
Brakes, steering, and suspension
With the car on the lift, the underside tells the truth. Brake pads are measured in millimeters at each corner. Rotors are checked for scoring, lip, and runout; the decision between resurfacing and replacement is made against the manufacturer's minimum thickness spec rather than by eye, a judgment we walked through in our rotor resurfacing versus replacement article. Calipers are inspected for sticking pistons and torn boots. Brake lines are followed from the master cylinder to each wheel for chafing, corrosion, and secure routing.
Steering components — tie rod ends, inner and outer, the rack boots, ball joints, control arm bushings — are checked by hand with the wheels off the ground. Play is measured, not guessed at. Shocks and struts are inspected for weeping. The sway bar end links are moved through their range. On the sedans we most often see trade in at this point in their life — the G70, G80, and G90 — the suspension is engineered with tight tolerances, and the inspection respects that.
Cabin, electronics, and the details that reward a second look
Inside, every switch is operated. Seat heaters, ventilated seats, memory positions, steering wheel heat, massage functions where equipped, each window, each lock, the moonroof in both directions, the trunk release from three locations. The infotainment system is paired to a test phone to confirm Bluetooth, wireless projection, and the native navigation. Speakers are run through a tone sweep.
The diamond-quilted leather is examined for bolster wear and stitch integrity. Headliner, pillars, and carpets are checked for staining and odor. Climate control is run through its range and the cabin filter inspected — often replaced. Key fobs are tested, batteries replaced, and the number of keys confirmed before the car is cataloged.
Safety systems get their own pass. Forward collision warning, blind-spot monitoring, lane-keeping, adaptive cruise, and the 360-degree camera are each verified against the owner's manual sequence. Any stored diagnostic trouble codes are read, addressed, and cleared — then the car is driven and re-scanned to confirm nothing returns.
Road test and final sign-off
The road test is not a loop around the block. It includes stop-and-go, steady highway, a hard brake from speed on a closed stretch, and a quiet listen for wind noise at 65. The transmission is run through its gears under load and on deceleration. The car is then returned to the shop, re-lifted, and re-checked for anything the drive may have revealed — a leak that shows only at operating temperature, a sound that only appeared under lateral load.
Only after that final pass does the sedan move to detail and to the showroom floor, where it joins the rest of our available inventory. If you are researching a specific model — the G80 or the flagship G90, for instance — the inspection record for that individual car is available on request. The detail rewards a second look.
