Well I suppose there's no right or wrong answer here. Too many variability that can swing the decision into one or the other. It can depend on how far one travel, what is the traffic conditions regularly encountered, what cars considered (which like I said determine the depreciation and operational costs), how hardcore one is, how much income one has, other commitments, parking space availability, safety, etc2. For one guy can be better to own 2 cars as he has the means to own 2 and ok to drive any cars daily, but for another guy better to own just 1 that gives him enjoyment driving it daily and yet still not hurting him financially or elsewhere.
For example one travels short-medium range daily, with mostly smooth roads and not much jam, has no parking space for 2 cars, then having just 1 car that he likes is the best solution. For another guy, he travels longer thru more jams, no issues driving anything daily even low end cars, and has the means to own 2 cars, then maybe that's the better solution. So no right or wrong here, each is a unique situation with each own suitable solution.
