Hey guys just I just bought this 2005 Chrysler 300C with 250K on the clock. 0 dash lights and runs strong. I don’t know much about the mechanics of cars, but I want to learn. Is there anything I need to know to make it last longer? Anything I should replace immediately? (Got it from a grandpa so it’s Mint condition inside and out) any information will be greatly appreciated my goals just make those last as long as possible. I plan on keeping it stock outside of probably long tube headers, straight pipe and a tune. Is there anything that needs to be upgraded to make it last longer? I hear a lot about oil catch cans, etc..
