Hello, I have changed my tasted after riding on my friends BMW, totally different from my accord.

Anyway, I have been reading spec for M3 and 328i, however, I am not very familiar with BMW, can anyone help me? I am looking for year 98 or same generations.

Can anyone give opinions which one should I go...

Well the M3 has a considerable amount of extra power (240 vs 192) and sharper handling, but it'll cost you more to get one. The 328i isnt slow by any stretch of the imagination so if you cant afford an M3, a 328i is a very good 2nd best.
