I have a '06 Volvo V70 that I use mainly for commuting to and from work (about 10 km each way), with the occasional longer trip of up to several hundred km every few months or so. I drive maybe 7000-8000 km/year and the car has gone a total of approximately 155,000 km so far (I bought it from the dealership four years ago). I don't have access to a parking garage so the car stays outside nearly 100% of the time.
The car currently gets a routine service once a year according to Volvo's general recommendations based on mileage and age (the next being due in a few months), as well as attention when the car systems indicate that something is wrong, but not really much else in terms of specific servicing. Things like that I recently replaced the battery because it was nearing the end of its servicable life (which didn't surprise me much, given my driving pattern) and before that had the cam belt replaced due to age when the car was approaching the ten year mark.
Given that I drive mostly short distances often, are there any particular additional steps I could or should be taking that will help keep the car in good condition for as long as possible?
