SOURCE: Approximate cost of alignment for 2007 MB C230 and

If he vehicle need alignment it will have uneven wear on inner or outer of the front tires. Unless a vehicle has been in an accident or steers funny (pulls to the side on flat road or track odd) I would say save your money. 69K on tires is good to great i would say. Tire rotation is the best thing you can to to extend tire life. AT 69k on a set of tires i would save the money for the alignment and go have dinner at a nice restaurant. Mu guess is they will get you for around $120.00 or more. Watch for the old alignment you need new front end parts SCAM. If the thing drives good no shaking or loose steering enjoy your car and a good dinner and brag about your good tire life.
