I find that insulting, as I drive a Vauxhall, you can't class them all the same!
Terrible news. I hope you find it. Why would anyone steal a Vauxhall though, is it because they're nondescript and easy to pull off robberies with? I hope nobody pulls a robbery off with it.
Happened to me once, not a Vauxhall but another type of car and I told my insurance company that I didn't want it back, even though they found it, you never know how they've driven it do you.
Hope you get it back.
