We use a 91 300TE for our shop delivery car. We have had it for about 3 years and about 75k miles. I hope we have serviced it as I can't really remember doing anything to it, it is constantly on the go during working hours.
Great cars, among my top choices for low cost long term transportation. Absolutely the top if a SW is a priority. Rear seats tend to be more uncomfortable in the wagons. This would be my only consideration. It might not be as good a real estate showing vehicle as it would seam, otherwise, due to this. Does fine for kids.
