As far as I could tell, my e30 was more responsive on the excelerator than the e36 I drove. The ride is alot more vivid in the e30 due to its shorter wheel base. You get a much more raw feel out of it. Also its smaller size coupled with its peppy engine, awesome gear box, and suspension to die for, it sort of takes on the role of a street worthy go cart. My suggestion to everyone is if you dont mind shifting all the time, get a manual e30. Its better all arround.
I found the e36 to be more civilized in its ride, power, and comfort than the e30. That I liked. If you are looking for a cheep weekend car that blows your mind, I would suggest an e30. I drive mine almost every day, but thats just me.
I would like to see two stock 325I bmw's one e30 and the other an e36, duke it out on a track. I think it would be a pretty close one.
