At 129,000 mi I replaced the plugs,igniti on coils,belt tensioner and belt,PCV,M AP sensor,water pump,new aluminum coolant crossover( by plastic), aluminu m thermostat housing and thermostat ,upper & lower radiator hoses,new all aluminum oil filter housing(by plastic),n ew lower& upper intake manifold gaske ts,cut out the plastic heater core "Tee" and installed a metal 1"x1"x1/2" and ne w hose clamps,flushed and refilled OAT antifreeze,drained trany pan and put in new oil filter and new trany pan"with a installed drain plug" in it,replaced the 3.5 qts of synthetic ATF+4 transmission fluid that come out of it and used the trany fluid check stick at 150° F throug h the "dealer only" trany fluid tube cap to 63 mm measurement trany fluid leve l,replaced both upstream O2 sensors, cleaned the throttle and throttle body, put on a new lower engine oil pan( that the oil change shop stripped the drain plug threads out on) changed the 5W-2 0 synthetic oil,and drained/ pumped out all rear end gear lube oil and put in new 75W-140 gear lube. I figure,that, my 2014 charger SE 3.6L should be good for another 100,000 to 200,000 miles ( of course,I will drain an d refill the trany fluid again after 10,00 0 to 15,000 mi to bring my fluid ratio up to 75% -90% clean/ new trany fluid) . I've already brought my MPG up from 18 mpg to 26mpg Lesson and advice--"take care of your car/ investment and you won't have to spend another $30,000 to $90,000 for/on a new car' (I call "the junk and crap cars of today)". Personally-im considering a 1960' s to 1970's dodge,Chevy SS,Pontiac,cuda,or GTO of yester-year I remember owning and diving in my youth( 45+ years ago).
