I have a 1986 300E.I was reading in the Illustrated Buyer's Guide:Mercedes Benz, by Frank Barrett, about the '93 300E and '94-95 E320.It says:"Displacement was nudged from 3.0 to 3.2 liters,and a new four-valve head utilized variable intake cam timing.Power jumped from 177 horsepower to 217.Peak torque increased, and variable cam timing provided a flatter and fatter torque curve.The four-speed automatic transmission,which had previously started in second gear,was altered to start in first gear,improving take off.The transmission is electronically linked to the ignition system so that timing is momentarily adjusted to smoothen shifts."I was thinking of trading up to either a '93 300E of '94 E320. I assume the difference between the '93 and '94 is pure cosmetic changes.I just bought the '87 300E last year,and it had 72,000 miles, and it now has 82,000.Is there a dramatic difference between the old 300E and the new engined models?Is it worth trading up for?Or should I wait to get the '96 E320, which has even more changes?
