Rusted wheel studs.
Who was the last person to touch the wheels before the accident? Wheel stud should never rust significantly, they are covered by the rim & lugnut. That Mazda must be a real let down in the power dept. I'd get angry with the power and thrash it harder in the end = same fuel economy probably. What car is next?
If you have a few bucks to buy & maintain a B5 S4 is really fun and you get AWD for them Orangeville snowstorms. If not, a B5 A4 chipped with exhaust & lowered is an amazingly fun car - I used to own one![]()
