I've not owned a 240, but I had a 740 years ago (my son was young and my wife was its primary driver). Pedestrian handling, somewhat like the mid sized Mercedes Benz of that same era, but with heated seats and a heater like a blast furnace it was great for the trips to Maine and Wisconsin.
As for the implication that you need to be a race car driver in order to discern the difference between the handling of a Volvo and a BMW, this is actually pretty close to what I tell people when they ask me whether to buy a BMW: drive one and characterize the way it handles and feels and responds. If you don't conclude it is much better than whatever else you are looking at, don't buy it. BMW is not for you. BMWs were built by Germans, and Germans maintain things. Hence BMWs are designed to be maintained, and this maintenance requires some amount of effort on the part of the owner. If you don't believe the character of the car is superior, you won't be motivated to do the proper maintenance, then your car will become unreliable, and you will be doubly unhappy.
