Dealer visit checklist

2025 Mercedes-Benz GLC checklist

Print it or keep it on your phone. Tick each item as you go so nothing gets missed.

Inspect the car

Check every panel gap and look for mismatched paint (signs of past accident repair)
Look at the tires: even wear, matching brands, at least 4/32" tread
Check under the car and engine bay for oil, coolant or other leaks
Start the engine cold; listen for knocks, ticks or squeals and watch for smoke
Test every window, lock, seat, light, the A/C, heat and infotainment
Test drive on city streets and highway: straight braking, smooth shifts, no pulling
Ask for the service records and a vehicle history report
Have an independent mechanic do a pre-purchase inspection (about $100–$200)

MBUX infotainment glitches and software freezes reported on early 2025 build weeks, often requiring dealer OTA updates
Air suspension components (optional on GLC 300) can develop leaks after 60,000 miles, with repair costs of $1,200-$2,500
Turbocharged 2.0L M254 engine oil consumption between services is a known watch item — check levels every 5,000 miles
Panoramic sunroof drain lines can clog, leading to interior water intrusion if not flushed annually
Advanced driver-assistance sensors (radar, cameras) are expensive to recalibrate after windshield replacements, often $400-$900 at dealer

Know the typical price: about $47,000 for this model year
Negotiate the out-the-door price, not the monthly payment
Get the full price with every fee listed in writing before you sign
Bring your own loan pre-approval so the dealer has a rate to beat
Say no to add-ons you didn't ask for (paint protection, VIN etching, nitrogen tires)
Negotiate your trade-in separately, after the car's price is agreed
Be ready to walk away; another listing is usually a click away
