Sorry if this is another one of "Those" threads...

I'm looking at the cracking deals you can get on the Vectra and Signum 2.8 V6's out there at the moment...

£3-4k for an Elite with all the trimmings, power, low miles etc...

So I'm curious what people get out of it if they are using it as a commuting car? I currently do around 20k miles a year with a minimum 90% of my driving life on the M1 cruising along at 70.

My Saab TTID is a great car, but I just dont enjoy driving it and the wifes Vectra 120 is even more of a bore. I really miss my 2.0 T Signum and am on Ebay/Autotrader all the time looking at whats out there.

I used to get around 300-400 miles from a tank in my old car but that was more 50/50 driving, never pure M1, so I cant compare the Derv with the Petrol. I've never had less than 650 miles from the 58 litre tank in my 9-3.

I've also done a insurance quote online and believe it or not a 2007 Signum 230 V6 is less to insure than my 9-3 180 TTID.

I've sort of convinced the wife its a good idea, I'm just struggling to seal the deal in my own head.

Opinions greatly received...
