The work you described could be called serious, but for these cars it is routine. Then there is the serious routine work, which includes the rear main seal, AC, etc. My wild ars guess is around $1000 at an indy mechanic for what you need done.

I suppose however if you are driving down the road, the strut towers are squeaking like mad, the steering wheel lurches because your CV joints are shot, and the engine is vibrating like mad, you could call this work very serious!

Good luck.
