Hi Michael - in fact, I figured that part out as well. Apologies for taking this thread off-topic for a bit.
Barring technological breakthroughs and developments, that can render a car technically obsolete (as our Pagodas actually are, mostly due to safety and fuel consumption advances on later cars), my modern Volvos from an economical standpoint should be kept until such time as technical obsolescence sets in. This could be another twenty years. Best never to sell in the meantime, but keep investing in the smaller and larger maintenance it requires. I figured (again, in my head while driving last night) the engine and transmission are the main investments to be made every couple hundred thousand miles. Everything else is minor stuff: brakes, struts and shocks, etc. The total cost of maintenance including that occasional engine or trans overhaul, on a yearly basis, comes down to peanuts when compared to the lease or buy cost of a new car of equal class. So my advice: buy a reliable (dare I say Toyota?) car that's about 8 or so years old, very low miles, very well maintained (they are a dime a dozen) and keep driving it and maintaining it until technical advances render it obsolete, then move on to that newer technical generation. Besides the enormous savings on depreciation over a new car, don't forget the equally sizeable savings on interest, given the far lower average investment amount, and the insurance: really no need for comprehensive coverage on a car that you can replace if lost for say $5,000.
In my opinion, we've not seen really much advancement in the last 15 or so years. My two Volvos (from 2002 and 2003 respectively) have air bags all around, are very fuel-efficient, have ABS and many other active safety controls and also have all the comforts of today's cars (and fortunately lack the kinds of features that have me acidentally calling help desks when I touch a wrong button in a modern rental Honda or Buick whenever I'm in the States). And, big point: they don't rust. So I do plan to keep them for at least another 10-15 years.
Back on topic!
