I would take a look at the S4 if your looking to keep some power. The standard A4 is kind of blah for me.

 

I was looking at a 3 series, C class and A4 before I bought my IS. The gas mileage in the S4 killed it for me and the insurance and maintenance were the final straws. Think about that. I'll post a pic of my boy's sick G sedan. I drove it the other day an it's nice and comfortable.

 

The g37 is probably the fastest out of the ones you mentioned (bar 335i). The C350 is elegance, and the 335 unreliable. I would stick to a 4door g37 manual or a C350. The Audi A4 is by no means "rare", I see them everywhere.

 

G37 would be the best option, I also considered one before buying my IS....

 

yeah i wanted a g37s for awhile now. but my friends has it so i want to avoid it. you also see a lot more g37s in the hellaflush scene and stuff. you hardly ever see a MB in the scene. I want to be different and stand out. And im picky with my car bodies lol. I like a 4 door thats boxy and the MB are boxy and love the look of it! And if i were to get a 2 door it has to have curves. But im going to go test drive the MB today and hopefully it impress me. One thing im iffy about is the interior quality on the C class...

 

Here's my buddies G sedan. It's SICK!!!!!!

 

SICK for sure! but i think i made my decision on what i want. i think im going to go with a 09-12 body style audi A4. they look just plain sexy and as well have lots of aftermarket stuff to it where i can boost up the power and thats something i been craving ever since i had the is350. so disappointed that these cars cant gain for ****! also i been wanting to have that "pssssst" noise hahaha
