I'm interested to hear your comparison and the results of the work they did!Update:
My car has now been in the shop for 2.5 weeks. As of two days ago they're still waiting for some part to replace the oil pan seal. Apparently the rear main seal has been replaced. Not sure if my engine is back in the car yet and I definitely don't know when I'm getting my car back. Since day 1 I've been driving a G70 3.3 Prestige loaner car. I'll have many comments about driving this car compared to my 3.3 Sport.
