I have a Mint 1994 850Ci with Autothority chips and I love the car. I test drove a 1994 850Csi the other day at a dealership in Boston. Now I understand what the 850Csi owners are talking about...it is a beast in comparison. The 850Ci is still an awesome vehicle and has plenty of power, certainly enough for me...plus a 6 speed would drive me nuts in traffic. Both are great, but achieve different goals. The 850Ci - a fast exotic cruiser, The 850Csi - an explosive sports car. No offence to my fellow 850CiA or 850i owners.
