I've just discovered this forum. So much to read.
I've had my Omega estate for almost 10 years, since nearly new. (Ex Vauxhall management with 2000 on the clock). For 6 months it had recurrent alarm faults that drove me mad and resulted in lots of warranty action at the dealer. My guess is this is why it didn't get used much before I bought it.
Suddenly it fixed itself, the mechanics didn't do anything different, and I've had no trouble since except a single fuse blowing and a rear light bulb failure at different times. Other than that it has been totally reliable.
It is by far the best car that I have ever used, the performance is good, it's very comfortable and it can carry surprisingly big loads when the back is flat. I wish they still made new ones, although this one is carefully maintained and still going strong so looks good for a few years yet.
My family love the car and as the kids have learned to drive they have asked leading questions like 'Are you going to change your car soon?' or 'How much is it for me to go on your insurance?' They don't want a hot hatch they want my Omega so they can move their guitars and drums and other junk.
