2015 SLK 250
Just bought a 2015 250 and prioritized the work to get it headed in the right direction had spark plugs replaced by local indy I trust. looks like water got into coils... during engine detailing we're guessing? still operable thank goodness... so moving forward New Mich tires from Costco. soon brakes on all four corners. Is there something else I should consider i would like to just enjoy the car next few months and do transmission filter/fluid change after summer it will still be before scheduled milage this fall. thoughts?
