The 320/6 is basicly a little brother of the six cyl 323i. The 320/6 however has a 1.9 liter six, instead of the 2.3l six. The 323i has 143bhp while the 320/6 has 122bhp and 118 ft./lbs of torque. If I'm not mistaken I believe the 320/6 is carburated and not fuel injected. I am guessing that this car would go to 60mph in about 9 or 10 sec or so, and top out at 110mph. The 320/6 is very rare and is a euro only model. That in its self makes it slightly more desirable than a US spec 320i.Good Luck!
