I have a 9-5 SE 2.0t, nice enough car to drive around, not really a driver's car though - remember they are based on the vaux. omega chassis.
As long as you are not hoping for a dynamic drive and just need something to cruise up and down the motorway they are great - you get loadsa toys for your money compared to say a BMW.
Parts are expensive though, try £650 for a new throttle body, £150 for an ignition module which is known to fail regularly
Given the choice again, I probably would get a 2.5 mondeo - Ford through and through me...
