For maintenance I would think you could do something to estimate the differences, by creating a list of things that are likely to go wrong in each car with estimated costs and how often they are likely to go wrong, along with estimated costs for consumables. That would allow you to at least begin to quantify how much more expensive a 35is is likely to be to own than a 23i etc. I think that could be really useful for prospective buyers.Hi there ..of course you’re not being a dock…reasonable questions ..
So..
Of course what I’ve posted is subjective but the key question is how can it be anything else but subjective.? There are no data sets that can give us anything approaching a statistical or scientific assessment of these different issues.
What I have done is to integrate a huge body of empirical data accumulated over 10 years of looking at six or seven Internet forums and countless Facebook pages to draw some conclusions and in addition over 4000 hours of driving time spent with a multitude of Z fours in a variety of conditions I think I’m entitled to offer subjective opinions on the matter that are probably better validated and better reason than most others.
Take a simple example of post about roofs and engine problems with N 52’s. How many post occur across the Internet and forums about problems with rules probably five every day how many posts are there on M5 two engine problems apart from some van issues hardly ever therefore it’s not unreasonable to say that E 89‘s suffer from roof problems quite extensively and the N 52 engine is relatively trouble free
I’d be very pleased if somebody actually produced a well structured book on buying an owning a Z4 but all I see is short soundbites from people with limited experience offering I highly personalised opinion therefore I’ve decided to produce her a book covering all these matters and we’ll see what the market decides in terms of what people think about it .

This is absolutely and the reality of things when one is making a decision to buy.
It actually bought my Havana Brown 35i based mainly on the fact that I loved the colour combination. The fact that it was a manual 35i scarcely enter into my head. Yes, I wouldn’t have bought it if it was one of the much lower performance cars but considerations like ‘weight distribution’ didn’t enter into. I never track my cars and to be honest, I doubt, given that I am just a ‘normal’ driver, that any supposed subtle nuance of weight distribution would actually make any difference to my laptimes.
Having sold that about 6 weeks ago, the same essentially principles applied to me now buying my Valencia Orange 28i Automatic. It was first and foremost the ‘look’ of the that sold it to me. Would I have bought it any more or less readily if it were a 35is? No. Did the fact that it’s pre-2015 put me off? No, not really. I will get the known pre-emptive measures done and absorb the cost.
We perhaps don’t like to admit it but one of the highest ranking, if not the highest, criterion in our decision-making to buy a car (any car) is entirely subjective. It is aesthetics. Whether we like what it looks like. That is impossible to quantify.
I do think the spreadsheet does have some utility though. Particularly, for someone who has no knowledge or experience of these cars. It affords some framework for someone to visually compare things. They may, for example, note that a particular model appears or is suggested to have higher maintenance or running costs and they my then wish to explore that further and understand why this is suggested, perhaps?
The big issue is probabilities…some folks have run up last £15k on 35i/35is repairs ..with BMW or Indy’s..others smaller failures fixed at home…For maintenance I would think you could do something to estimate the differences, by creating a list of things that are likely to go wrong in each car with estimated costs and how often they are likely to go wrong, along with estimated costs for consumables.

Lots of estimates, but ball park figures would still be worthwhile.
I respect the idea and the effort in doing this.
That's pretty much where I'm at.But I have steadfastly refused to drive a newish 6 cylinder Boxster/Cayman because I know I would be devastated as to how “uncompelling” my BMWs would be in comparison. And I have a ZM as well as the E89. It’s just as well there is a huge financial delta between them (so I can’t afford the change) and that frankly Boxsters are essentially chavvy (my view only). And as a continental cruiser the E89 is not bad at all. All I would change is slightly less road roar (but then Boxsters have this too). Long live the E89!
