Well a 1995 325 really isnt valued that high and how many miles are on the car? Why dont you part your honda out and sell it stock and then buy the car cash from him, the M3 bumpers really to be honest are not that expensive and pretty easy to pickup. Also the M3 market has fallen dramtically and you may be able to find an M3 in rough shape of course for 5-7k, there is a huge leap in performance from a 325 to an M3, I have a 95 M3 and own a euro specific shop so we get 2-3 M3s a week in for service. Good luck with whatever you decide to get and welcome to the euro world!
