I've got a 2005 320d SE Saloon. I bought it last year as a temporary car when i was doing 2k miles per month. Since then I've fallen in love with it. It's a fantastic car, all the power you ever realistically need, certainly tight and agile, and mid 40's MPG.
Okay so it looks boring as fook to look at, but i'm happy to forgive that for the driving ease/pleasure, and when it comes to it, enjoyment. I've definitely been able to push on as hard as i did in my zed in it.
Mines on 119k now, but it drives absolutely impeccably.
