Same re the Omega, but soooo many of them seemed to be ex-police cars when I looked more into actually buying oneI always fancied the 3.0 v6 omega back in the day, rwd bargain barge for the motorway!
Recently had a Saab 9-5 for 4* years from the GM era, on the whole not my best purchase, but I liked it all the same. Aside the seats, the build quality was not great. So I'll assume vauxhall would be a grade down.
Edited

not the best car but had a bit of a following.
