You'll love it mate - I had a 50 mile journey home when I went to pick up mine, and I loved the drive back. The 35i just has so much power and the sound of the beast is just amazing.
be careful with the marks the seat belt will make on the top of the seat, near your shoulder - and thats about the only thing to watch out for. I used a litre of oil for the first 3000 miles - but also before you pick it up, go thru the vehicle diagnostic to check the miles left until brakes need replacing etc...
You will love the music hard drive to save your CD's and memory stick music to, and the DCT is superb too...
Stone chips are a problem, so get a touch up stick super quick too....and thats it!!!
