I cant say to much about the 240 series myself, ive heard there supposed to be safer, but i cannot see why, as the 700 series has the same massive bars in the doors too, dont know i feel the Wagons are the safest of all being the wheel base is longer which makes ( in a study i read ) for a safer impact, though i personally have only wrecked a 745, i have also looks at the wrecks at the junk yards seems the only weak spot on the 700 is the rear quaterpanals as they crush all the way in and will let the frame in that area bend alittle more then it was probly designed to, but being the passengers are before that area no biggie, biggest problem with the 700 series is the cost of parts once you wreck one say goodbye.
