Hi guys,
Bit of a newbie when it comes to BMW's as i have not owned one before. Current a VAG fanatic!
At the moment i own a mk4 golf GT TDi 150, and the E46 shape 320D M sport convertible has caught my eye which I intended to purchase towards the end of the year.

I would be grateful if someone could give me some pointers as to what to look out for, especially with the 320D engine and the convertibles.
The cars i am looking at currently have between 70-100,000 on the clock.

At the moment, i have read up about the swirl flap problem and when i do purchase one, this will be my first mod!

If there are any links to threads where this has already been discussed, it would be much appreciated if you could point me in the right direction.
