hey congrats ! that's an awesome color. is it a manual or auto tranny ? any rust ?

i'm brand new to the 240d owership too. i bought an '82 240d manual 4 speed about a week ago and drove it back from CA to MN, 2000 miles. this car is slow to take off but maintains speed at cruising well. we tested out different cruising speeds from 70-85 range. i broke my alternator belt at 85 cruising so it could have been a bad belt (brand new, just installed it before the trip, could have been too tight.) i would say 65-70 is ideal for me personally. it has nothing to do with mechanical preference, just the right amount of engine noise and still hight enough rpm's to go up a gentle hill. i think you get better milleage if you decrease speed.

the PO walked me through the vents, its a little different. the two sliders are for defrost and footwell, look at the little white arrows, they point up or down. if you have them both together, then both is off, and if both are completely apart, then its max. the slider next to the ac is for fresh air which blows heat but not ac or vice versa, can't remember. i just know it doesn't do both. avoid having everything close and turning on the fan, it will blow the cover off the vents (i've heard.)

my temp gauge reads around 85 at cruising speed. it went up to 120 went the belt broke. oil pressure gauge pegged at 3 at cruise but drops down when i stop.

enjoy !
