I dont mean to sound rude, but E60 M5 on a student budget!? With the list of other cars i am starting to question the student loan system!!!
On a serious note;
Best feel for the $$$; higher ratio diff
Best power for the $$$; Headers/exhaust
Best power for single mod; Supercharger (easy/reliable, unlike turbo or NOS)
