Dealer visit checklist

2025 Mercedes-Benz C-Class 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 requiring dealer resets have been reported on early 2024-2025 units
Mild-hybrid 48V system (EQ Boost) can require costly repairs outside warranty — components run $1,200-$2,500
Air suspension optional upgrade shows higher wear rates; standard suspension bushings typically need replacement around 60,000-80,000 miles
Turbocharged 2.0L M254 engine requires premium fuel exclusively and has shown oil consumption sensitivity if service intervals are stretched
Panoramic sunroof seal deterioration leading to water intrusion has been a recurring complaint carried over from prior C-Class generations

Know the typical price: about $44,000 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
