I've got an 03 cobra with 450rwhp but the creaks and clunks during lower speeds is starting to annoy me more and more. I'm throwing around the idea of either a bmw 335 or mercedes e55 amg. I'm worried that they wouldn't have that real seat of the pants acceleration that I LOVE in the cobra. So my question, would I be satisfied with either options or would they feel painfully slow compared to my cobra. I'm aware of their acceleration specs so their clearly both quick, but are they too refined and quiet to get that same seat of the pants feel? Thanks guys.
