Driving habits vary some. Used to put 30-35,000 miles on. Now I usually fly the longer trips and rent a car.
Currently, putting about 10K on my 88 Saab 9000turbo, city/suburban/some highway. The 85 Saab gets lots of short trip miles (wife drives it).
85 Volvo 245 turbo gets few miles, and they are varied but mostly within a hour of home.
Daughter puts on about 15,000 a year, mostly to and from work in downtown DC (think that qualifies as city).
Dodge van gets run to Richmond, mostly highway, about 220 miles round trip, maybe 25-30 times a year, and locally only to help in Rotary Fruit Sale/Rotary Memorial Day beer sales.
However, I do move about $8-10,000 worth a month through my garage, and can assure you it is used in almost any kind of driving you can think of!
