I didn't uncover this until yesterday as I was changing the license plate holder on my '08 Z4.
Behind the license plate, on the fender, there is a sticker with the VIN number. At least on my car, there is, and I have no reason to believe other Z4s are similar. I wondered about the purpose of it, and I suppose there is one, but reached no conclusion.

There isn't really any problems to look out for on the z4. They're pretty solid cars and the engines are near bullet proof. As long as all the proper maintenance has been done over the years and have had no accidents you should feel pretty comfortable buying the car. The z4 was also my first BMW and I love it. Ohh. Tires are the biggest thing. These cars have a trimmling problem. The source is almost always low grade tires. Runflats ride like crap. Continental dw or dws tires are the most favored for these cars.

And the vanos seals dry out over the years so those might have to be replaced. But nothing to worry about.

Not on front fender, on rear fender. Nevada is a two license plate state but not enforced. I have nothing on the front of mine (except for four holes).

I see, does it mean there is no VIN stickers on front fenders?

Hikari, what year are you looking at buying?
When you go to test drive make sure to rev up the engine, I found out my car needed a new throttle body on the first week of owning it....awesome!
Best thing is to pay for the pre-purchase inspection by a dealer who can see all the BMW codes, not just the OBD codes.

Yep thats what I am thinking to do when I have test drive, I want to check for some unknown problems before I get the car
Probably getting 05+ with decent mileages; what mileage would the z4 engine would need to be rebuilt?

Carry a small air pump with you and a can of sealant. This will get you to a tire shop in most cases.

Roof drains get clogged & the roof motor ends up sitting in water - have to remove the roof to replace it
If it's a private sale maybe you know it was garaged - if not worth looking into

Keep in mind that the E85 Z4 was refreshed for the '06 model year. A few minor styling changes and totally different engines.

For the '05 and earlier,
- The water pumps can fail at around 80k miles.
- "Sticky steering", which involves replacing the steering column.

For the '06 and later,
- The N52 engine can have some valve clatter. At one time they were replacing the cylinder heads but now I believe they are just replacing the lifters.

For all years,
- The rear springs can break
- The power top motor can fail because of the design puts it in the path of water. You will see a rash of complaints here every spring. There are some great articles here on doing a DIY fix.
- If you ever leave the top open and it rains, water can short out some of the electrical systems, the most common being the airbag control module.

Have any Z4 you are considering purchasing checked out by a BMW-knowledgeable mechanic and you should be OK.

BMW did not change the design of the steering until July '06. So any build before then will have the old design. I found this out when my June '06 build had the problem. BMW did pay for half the cost to replace it. Cost to me $1200.

..........
- For the water pump (and service belts), I agree on the failure rate. In fact, I replaced it, as preventive action, at around 90k,
- For the "Sticky steering" issue, though, it was unexpectedly resolved when ABS/DSC sensors (2 ea.) were replaced on the brake module. Since then the steering has been very smooth.

I have a 2003 and have this issue (sticky steering). Is it necessary to replace the column or can it be repaired (DIY)?

History of being garage kept is no guarantee of a dry top motor well. Water can accumulate via rainfall or car washes over the years, and it only takes a single leaf to plug the drain hole. My car had only 18000 KMs when I bought it a year ago, and is now at 24000 KMs, or 15000 miles. It has never been winter driven and its condition indicates it was always garaged. Nevertheless, I had to replace the top motor at considerable expense this summer. I suggest you get an inspection which includes a check of the drain hole condition.
