The 2003-on 9-3 has nothing in common with the older 9-3 (except the 2.2 TiD which was carried over) - the platform was entirely new.Thanks guys - i have now bought a 2007 "07" plate Saab 93 1.9TDI auto in black (i'm gonna kick myself for buying black the first time i have to wash it in our limescaley wiltshire water!) and i can confirm that saab learnt their lesson from the cracked bulkheads and moved the steering columb back on to the sub frame for the later 93's.
Everything else seems to check out ok on the car (spent a couple of hours checking everything i could!)
The bulkhead issue is not GM900/OG9-3 alone it's a GM2900 issue that affected Vectra A/Cavalier Mk3 and Calibra too. The new 9-3 was made on the Epsilon platform with Vectra C.
