Nothing, still only just running it in really.
The steering has been improved and the cabin looks a bit tidier. They've given me SatNav on the SRi, but taken away the rain sensors and electrodim rear view mirror, the stainless steel door caps. Still a very nice car and they have reduced some of the harshness of the 2004 SRi. This is my 3rd C vectra. The standard (2002) 2.2 was sloppy, the 2004 Sri was very good and this one continues the trend. Still would happily recommend the car to anyone.
Would you buy another car from this manufacturer? Yes
