I have owned both the F30 328i and 340i.

My impressions:

328i Sport: Coming from my former car, a 340hp S4 V8 it actually didn't feel like much of a step down. The 328i is fairly quick and lighter than my S4. I drove it for 3 years as a commuter and not once did I feel like I didn't have enough power to do what I needed to do even in aggressive Los Angeles driving. I took it through the canyons a few times and it was still fun. Despite "only" having 240hp vs the 326hp 340i, I don't feel like the 328i is underpowered at all.

340i M Sport Track Package: WOW, I only owned this car for 3 months, but it's so much faster than the 328i!!! Sounds so much nicer too! I still think it's underrated at 326hp. Much quicker than my S4, much quicker than the 328i. Did it make the 328i seem like a slug? No. BUT, I did have a loaner 320i and it was like night and day.

If you can afford it, go for the 340i. The 328i isn't that bad though if you want to save some $$. Either way, go test drive them both.
