Welcome Advantec
As Yanto says, use the search facility on here - you will unearth loads of stuff.
I recommend a private sale car with BMW warranty still running (preferably with 0% excess). FBMWSH obviously with Aircon and Xenons as the 'must have' options.
Don't let higher miles put you off, equally so a car that has been tracked/modded as they are usually 'over-maintained' to a high standard.
