nothing to think about , just buy the fuggin thing !
Z4M will be even better but nothing wrong with the 3.0l version or get a 2002 E46 Mpower , they mostly going around the 225k mark.(perfect package)
Small mods done to the 3.0l Z4 and i have seen them run ahead of E36 Mpowers.
And make sure you fit the Mcoupe rims on it.
