Maintenance, depreciation Comparisons between BMW Z4, 325 Coupe and Porsche Caymen

[hwdq]

Hi all,

As part of the evaluation, I'd like to gather comparisons around average maintenance amount and annual depreciation amount, for BMW's Z4, 325 Coupe and Caymen.

Thanks in advance.

Subjective evaluation (IMHO only):

Based on Boxster stats, the Cayman would have better depreciation against the 325 and Z4 because of far lower numbers and badge desirability. Because of HUGE service intervals (30K km) the maintenance should be comparable to what's charged by BMW and Mercedes. 6 year old Boxsters still sell for S$150K+, but it is difficult to measure depreciation for this because price paid for Boxsters 6 years ago included CRAZY markup figures by Stuttgart, and this is much improved now because of PI activity. Considering that Boxster S is now 264K threabouts the modified depreciation is `only' 17K/year over 6 years ...

LOL. Actually if you look at these figures, makes little sense except in a presentation to the finance minister. Buy if you can and if you desire it.

a simpler way will be

(buying price - scrap value)/10

but that is if u drive for 10 years.

There's body value to consider also. This is taken from a spreadsheet if anything doesn't make sense I'm sorry.

(buying price - scrap value + body)/10

Yes the calculation is simple and correct. However, because body value is mostly guesswork, the simple answer is still to refer to similar cars though.
