BMW Z4 vs. BMW Z3 Reliability Comparisons

You won't find BMW Z4 or BMW Z3 reliability information like this anywhere else. Actual repair frequencies, not just vague dots, to make it clear how much the BMW Z4 and the BMW Z3 truly differ in reliability.

These stats are promptly updated four times a year, to much more closely track BMW Z4 and BMW Z3 reliability as the cars age. Others tell you how reliable the BMW Z4 and the BMW Z3 were a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the BMW Z4 and the BMW Z3 have been recently.
