Looking to buy
 

I am looking to purchase a 2010 challenger SXT. It has 198000 km.

Should I be concerned with the high km?
What else should I be looking for

Have the vehicle checked out by a third party mechanic. Normal things to check before purchase of any used vehicle. Maintenance history, accident history (if any), repair history, condition of suspension, brakes, tires, exhaust system, overall condition of engine, oil leaks, powertrain leaks (transmission, differential), lights, horn, wipers, electronics (radio, instrument cluster, interior lights), check for stored codes, make sure the check engine, ABS and SRS lights illuminate on the dash when starting, fluid levels.....basic things like that.

Might want to compression test the cylinders too. Even if it's not smoking oil.

High mileage means more wear.
