I think everyone here has given you very sound advice. 46k on a car going on 4 years doesn’t really seem excessive to me. One windshield for that amount of miles doesn’t sound like a big deal. The tire replacement history might also not be an issue. Lack of proper inflation/rotation could play a major part in all that. I’d concentrate on the service history of the car and if you’re certain it hasn’t been wrecked in any substantial way, it’s probably still a very solid car. My .02.
