A few reasons for me, mostly financial...Rene130i said:
Going from 15mpg to 50mpg (saving me around £2500 a year)
Going from £1200 insurance to £300
Servicing costs vastly reduced (I was spending around £3-4k a year on the scoob)
Plus I fancied a new car. I've been driving Imprezas for 8+ years and fancied a change (I also didn't like the new Impreza very much). The 1 series is a very different beast, but I "think" the handling is as good (although I've not driven it in anger yeat), and it's certainly a lot less tiring on a long trip or the daily commute. Loving all the toys as well
