Hi Boo34 and welcome to the forum!
You spec sounds really good already. The xenon's are a must if you can get them within your budget.
Also, why not go ror the 318d? I had one for 3 weeks whilst my car was being built and I was well impressed with it.
Leather trim is nice but I would rather lose the leather and have have the 318d and xenon lights.
The standard seats in the M Sport are really nice. I only had leather fitted as it's easy to keep clean when I've had my two little horror's in the back! otherwise I would of kept the standard trim.
