I agree that the question is valid and also that the car is old enough that the struts may be shot…and that dealers…and chain shops…and many private shops… are notorious for selling unneeded struts. I’d also add that the type of mileage is as much a factor as the amount of mileage…been on Mass Ave in Boston lately?
One thing I’m curious about is WHY the OP is having teh struts changed. OP?
