I'd like to suggest a discussion of a subject that has been on my mind for some time, but which I have not seen addressed in any comprehensive detail. If anyone knows of a source of a collection of research on this subject, I'd appreciate a response along those lines. In the absence (or regardless) of such studies, perhaps this is the best place to discuss, debate, and possibly come to some conclusions.
Hare are my premises: With very few exceptions, every new car begins to depreciate as soon as it is first sold. Initial ownership costs consist of largely of this depreciation, as well as insurance, registration/ taxation fees, and cost of fuel. Maintenance costs are minor and are sometimes even paid for by the manufacturer.
As time goes on, the depreciation typically slows and the registration costs drop. Insuring the vehicle stays relatively constant; premiums may increase as medical and repair costs increase, but the vehicle's replacement cost decreases. At some point coverage for comp and collision may even be dropped.
Fuel costs do not change significantly over the life of the car unless the annual mileage or pump price varies.
Eventually non-warranty repairs become a factor. Some model years are better than others, and (as with cost of insurance and depreciation) some makes are likewise good or bad relative to others.
Which brings me to my question: Which makes and models are the least expensive to own for the first few years, the next few years, and so on? In other words, which makes and models have 'sweet spots' where the cost of ownership is significantly less than others?
Further, at what point does a vehicles cease depreciating? At what point is a vehicle too expensive to repair relative to its value? At what point does a model, assuming it is kept in good operating condition, actually become a good investment?
I have the last 13 years of Intellichoice guides, which includes a lot of raw data, but most of it is projected, and none of it takes into account anything past the fifth year of ownership. As such, no vehicle has reached a point of terminal depreciation.
Im posting this to the BMW and Lexus groups because i have some experience with each of these makes, and each has a reputation for retention of value. In addition, many owners of these makes keep their vehicles for longer periods, do some of their own maintenance, and/or have confidence in purchase of models over 5 years old. It makes sense to compare similar vehicles, and in this case I am most interested in luxury and near-luxury sedans and coupes, as well as 'sports cars'. Longevity of model series is also a factor, and with that in mind, I'd suggest the focus be kept on the non-X, M, or Z BMW 3, 5, 6, and 7 series (we have 25 years or more of experience on these now), and the Lexus ES, SC, and LS models.
