I cant give personal recommendations for a 190K car, however I run two T4's, the older is a 120K 99 model which I have had for seven years. I service and oil change every 5K, and keep tabs on other non service items and have NEVER had any problems with it. My local Volvo mechanic would confirm what has already been said, that if you regularly service the car, it will probably last longer than you will. So my advice is if you can see a genuine service history, go for it as you will not regret it good luck
