They are great little cars.

As to the 617 it is a good engine, I prefer the newer 603 though.

They key to winter starting is to make sure everything is in top shape glow plugs, compression, battery, starter, synthetic oil ect. If the car is in good shape it will start. I would also plug it in.

Condition and maintaince history is everything. Ignore the odometer to a point. Also since you are in New England rust will be an issue. Look for it in the usual spots. MB's like to rust out under the rear glass, around the sway bar mounts, and under the battery. Jack points are another trouble spot.
