Making a review in hopes that it'll give someone else some assurance since I didn't see any regarding this particular service! I had my EGR Valve replaced on a 2008 Pontiac Torrent. Average time (according to Google) is 1.5hrs and the same frame was given when I dropped my car off; picked it up sooner than that with 30 min shaved off (granted the EGR Valve is easily accessible for my make & model) and the price is pretty fair I think ($136 pre-tax & $145 after). However, I did buy the part myself at a different automotive store so your guesstimate might be different. Pretty at ease overall, straightforward & in and out. Car sounds and feels like it's better already.
