This isra ther interesting, as my car is in the shop right now as we speak.
I'm in the middle of one of those sagas; got a flat tire so, after looking at dryrot, I decide to buy new tires. New tire goes flat -- again and again. I'm told the tubes are defective. Well, after much pondering I decide to buy new wheels. Remounting the tires, it's found that the inside stickers are still there, cutting the tubes. They put the tires on, out of balance. Take it back, they tell me the wheels are out of round.
Take it to another shop; three out of four wheels are unbalanced. But, axle is bent. Also, front bearings are bad. Today they called and told me they fixed the weak springs. Apparently they rearranged the slats -- but they are confident it's fixed and will ride better.
Aside from this, it's very common to have springs that wear down on these cars. The springs are re-arched or replaced. In this instance I don't need either.
Actually, in my case the stance isn't bad, except when you put things in the trunk -- then it's low. It'll be interesting to see how it stands when I pick it up.
