Do cars lose power as they get older?

Do cars lose power over time? For example, would a 10 year old BMW 3 Series with average mileage lose much power if serviced and maintained well?

Yes, cars do lose a small amount of power over time for a whole host of reasons, ranging from clogged fuel injectors to worn piston rings. If a car's been well-maintained, there shouldn't be a noticeable drop in power after 10 years, though.
