hmm...
If it was me, I'd pick the m3. But, I dont know the condition of the cars you're looking at, the price, where you're going to be driving it, or anything. The m3 is way way faster. Realistically youre looking at about 1.5 seconds quicker with the m3 on 0-60. But do you need it if youre just going to be driving to work then taking the kids to the park? Well yeah, I'd still want it. Personally I think the less overall round shape of the e36 add a lot to its aggressive stance and appeal. But then again the e46 325i has its perks as well. Its not like its a bad car in the slightest its just geared towards a different audience than an //M car. I think that enjoying your cars aesthetic appeal is overall more important than speed, so if you like how the 323i looks, I'd get that. But since youre spending the money its ultimately up to you.
