360GLi -90 221.0000km (dad's)
343DL -79 235.000km (dad's EX)

Then some dead ones of mine:
343DL -79 230K
340DL -83 232K
340DL -83 240K
340GL -86 234K
360GL -87 286K
340GL -88 293K
Then some unofficcial records that i've seen:
340DL -89, 379K B14.4E ORIGINAL ENGINE!!! (a friend of mine's)
Mine made a decent 327K with original B14.4E engine, and VERY GOOD compression after that, 13bar in every cyl.

360GL -85 445K, B200K original engine

360GLi -89 425K B200F original engine also.
It's strange how long theese volvo (and also renault) engines can make in a such car, and arctic country as finland. Here the temp is in winter at -30ºc and in summer +30ºc. Add 10ºc to both if it's extreme.

What could be the highest mileage 300 series car?
