Advice for buyers
What should I look for in a used BMW Z4 sports?
Z4s are complicated beasts, and the most common problems with the Z4 have been little electrical gremlins, so try out every electrical component on your prospective purchase to make sure it all works as it should.
Then while you are on your test drive, check for any excessive wear in the operation of the clutch and that the gear lever engages in a precise manner. Don’t be concerned by a heavy shift action, it was like that when new.
What are the most common problems with a used BMW Z4 sports?
Z4s don't tend to have many common faults, but do make sure the car you're buying has been serviced regularly with documentation to prove, as the timing chains on some engines can stretch and snap if they aren't lubricated well.
There have been some reports from owners of their alloy wheels cracking, requiring expensive replacements, too, so inspect the wheels carefully for damage. If you can, look through the spokes to the inner sides of the wheels to make sure there are no cracks there either.
Is a used BMW Z4 sports reliable?
This generation of Z4 didn't feature in our most recent reliability survey, but previous ones have shown it to be relatively reliable. BMW as a brand finished in a disappointing mid-table 16th out of 32 manufacturers in the same survey.
