The car will be beautiful. I'd pass on the x-drive (I had it on the '07 E90 but went RWD on the '09 E90 and '13 F30....just a little more fun in wet and snow), keep the HK and pass on the DHP as it may help get you closer to that $500/mo payment. At 15k/yr I think you're going to be more around $550-$600.
