I can't directly compare my experience as it was spread over 2 visits due to my own time constraints, but front + all 4 doors would probably have needed 3 days if I'd been able to leave it with them to do the lot in one go. As Rajesh said above, it will vary depending on various factors, e.g. how many other jobs they are juggling, how many can work on the same job at once, what techniques and equipment they use. 4 days to do an entire vehicle (possibly including windscreen, windows, headlights, small sections of fairly flat painted trim such as the inlays on sideskirts and front/rear aprons) plus the next day to correct and final trim isn't over the top, though I would (did!) note the odo readings before and after.
