Fun second car, wrenching at home for most things, but normally I leave bigger stuff too a mechanic. Fluids, breaks, some electronics, some engines stuff I am comfortable with, but no pulling the engine/trans, not going to redo much suspension wise etc. I have zero history on the car and from what I understand, it is a daily driver or was until the mentioned balancer issues.
Alberta. Yes we use salt/sand, but I have seen some pretty clean cars despite that. I know the Bonnieville is an H-Body and I know the chassis is different, but figured both have an L67 so enthusiasts of that engine, which most W-Body owners are, may have experience with both. I know the Regal and the Grand Prix pre-03(?) had an issue with rusting strut towers for sure which was a w-body thing. resources for H-body cars are pretty sparse and probably will become even more rare over time.
