Diesel fuel and cold weather - is gelling still a problem?

We are looking at buying a new car, and the VW Golf TDI (diesel) is one of the cars we are looking at. We live in a Minnesota, so the winters can get cold.

Is the gelling of diesel fuel in cold weather still a problem, or do current formulations mostly remove that problem?

In the winter, gas stations in those areas will switch to a different blend of diesel to prevent gelling.

You are probably going to need a block heater for those really cold nights.
