Well done on your purchase - that was actually my car from new!
A few things to put your mind at ease - it has had the phase 2 cylinder head fitted under warranty and had 2 new front seat covers fitted 2 years ago, the PAS is sorted as well with the later reservoir and pump.
If you give me some time, I will find a picture of the car the day I picked it up.
I sold it to Veloces in 2012, and at that point, it hadn't been crashed/ damaged, but was on its second windscreen.
I was the first 2 owners, so it has one owner less than you thought, I leased it from Alfa, then purchased it out of the lease.
I haven't seen it in 2 years, so I don't know what the subframe is like, though I did keep an eye on chipping and corrosion, especially where the paint gets blasted off the front wings by the big wheels.
Hope you enjoy it, it was genuinely one of the best examples and only had to go as the company didn't let you have a car that was over 4 years old.
