What to inspect on a used car before buying in Michigan

Start with the basics: paperwork and visible history

Before you open a hood, confirm the vehicle’s title status and look for consistent service records. Ask the seller about recent repairs, how the car was driven (commuter vs. long-haul), and where it spent most of its life — cars driven year-round in Michigan can show different wear than those from milder climates. If records are sparse, plan for a more thorough mechanical inspection.

Exterior and body: rust is the Michigan deal-breaker

Rust is the most common long-term problem for cars driven on salted Michigan roads. Inspect wheel arches, rocker panels, door sills, the trunk lip, and under the hood for bubbling paint or flaking metal. Surface rust can be treated, but structural rust around suspension mounts, frame rails, or floor pans is an expensive and often unsafe repair.

Tires, wheels, and alignment clues

Tire wear tells a story. Uneven wear across a tire or feathered edges usually indicates alignment or suspension issues — common after winter pothole damage in Michigan. Check tread depth at multiple points, look for dry rot on sidewalls, and inspect wheels for dents that can cause vibration at highway speeds.

Under the car: suspension, exhaust, and leaks

On Michigan roads, suspension components take a beating. Bounce each corner of the car to assess shocks and struts — the car should settle after one or two bounces. Look for torn boots on CV joints, oil-soaked bushings, and fluid leaks under the engine or transmission. Exhaust rust near hangers and joints is common; a few surface spots are manageable, but holes or loose hangers are signs of near-term repair.

Brakes: pad life and rotor condition

Inspect brake pad thickness and look for deep grooves, rust buildup, or uneven rotor wear. Listen for grinding or pulsing during a short test drive. Given Michigan’s frequent wet and salted roads, check for seized calipers or excessive surface corrosion that can impair braking performance.

Engine bay and fluids: what to look for

Check oil level and color (dark oil isn't necessarily a deal-breaker, but milky oil indicates coolant contamination). Inspect coolant for discoloration or heavy rust sediment — cooling system problems are worse when temperatures swing in Michigan spring/fall. Look for oily residue around valve covers and evidence of coolant leaks near hoses and the water pump.

Electrical, battery, and heating

Batteries and charging systems suffer in Michigan winters. Check battery terminals for corrosion and ask how old the battery is. Test lights, HVAC (heater is vital), windshield wipers, and defroster operation. Weak heating or intermittent electrical issues often surface in cold weather and can be tricky to trace without diagnostic tools.

Interior and safety features

Inspect seat frames and floor areas for rust under carpets (particularly where foot traffic and salt may collect). Test all seatbelts, airbags (dash warning lights should be off), and safety features like horn and mirrors. A clean interior doesn’t always mean a well-maintained car — check beneath the surface.

Test drive like a local: simulate Michigan conditions

Drive on a mix of surfaces: highway speed for engine/drive-train behavior, local roads with potholes to reveal suspension and alignment problems, and a short downtown loop for low-speed shifting and braking. Pay attention to vibrations, clunks over bumps, harsh shifts, or hesitation — these are telltale signs of issues worsened by our Michigan roads and winters.

What a professional pre-purchase inspection will add

A trained technician at Garrett Auto will do a lift inspection, check suspension and steering components, perform a battery/charging load test, and scan for stored electrical or powertrain trouble codes. This deeper look uncovers hidden problems a quick drive-by won't reveal — and can save you from buying a car that needs immediate, costly repairs.

Real-world Michigan examples

Example 1 — A used car advertised with “low miles” looked tidy, but a brief undercarriage check revealed heavy salt buildup and surface corrosion on axle housings. The buyer avoided a car that would have needed suspension work before the next winter.

Example 2 — A buyer in western Michigan chose a car with worn front tires and uneven wear. A professional inspection found a bent lower control arm from previous pothole damage; replacing tires without addressing alignment would have wasted money and left the car unsafe.
