115k on my odo (bought new) and had the steering lock fail, which was fixed via recall. other than that no issues. just do your research into the history of the vehicle, service, repairs, etc... and you should be ok. don't get yellow, it gets tickets lol

It really is hit or miss. I would personally suggest to say away from 09's. While the CSC is a known issue, there are aftermarket solutions available.

The S4 isn't bad, but I wouldn't consider it to be in the same category as this vehicle. The Z06 is a monster but, as you mentioned, the interior isn't as refined.

The 335i is a great car (especially with the N54), but as you mentioned, the maintenance is FAR beyond what you would ever pay on the Z. The reliability on the block is great but the rest of the car is not.

If you're looking for a reliable ride, get a Z and expect to get the CSC fixed at some point. If you're into HPDE's, expect to put in a moderate amount of work to not have to deal with a decent amount of downtime between groups of laps.

Thanks guys. So what is the cost to fix the CSC? Is it a one time fix? At what mileage does that usually hit?

It seems that's the main problem, am I correct?

It can happen at any time. The HD part is around $300 if I remember correctly. The catch is the labor to drop the tranny.

There are always issues. All cars have them. But the Z is very reliable: Consumer Reports names most reliable cars - Sporty car - Nissan 370Z (13) - CNNMoney

It's probably the most reliable in it's class. Anything more reliable is either going to cost more or have a lot less power.

If it's a stock car, I think it'd be no problem. The Z is naturally aspirated so fewer parts to break and maintain and there isn't any super fancy tech going on here, just you standard electronic systems, plus SRM. None of those parking assists, lane change assists, blind spot indicators, pop up speakers, etc with little sensors or motors that could break easily. Just change that damned steering lock haha.

Reliability is hard to quantify when it comes to sports cars. Some people drive them like an old lady and some drive them like an old lady on crack. The main issues that have popped up are as follows:

-Oil Consumption (few reported claims on early models)
-CSC failure and/or master cylinder(prevalent and will fail eventually)
-6-speed Transmission Problems (grinding/bad syncros)
-Steering Lock issue (Covered under recall)

Forums like this tend to over-exaggerate issues especially when you see 50 threads on the same issue. I have an '09 with over 42k and the only issue I've had from above is the transmission grinding into 5th gear. I'd say it's about 9/10 in terms of reliability, but then again, that's from my personal experience. Some have had better, some worst. It all comes down to how the car was treated, proper maintenance and a little bit of luck.

Be extra careful when doing your due diligence on a used sports car. I would make sure it's stock and lowest miles possible.

The Z does have a few issues, what years are you looking at? I would steer away from an 09. Late 2010s and up will be your best bet.

In addition to everything people have already stated, the n54 335i has a history of HPFP (high pressure fuel pump) issues related to the direct injection system. When I was looking at cars, my sense was that in the 335i/s community, HPFP was kind of like the steering lock problem with the Z... except there doesn't appear to be a reliable fix for the HPFP issue... and steering lock just means you're stuck at home or in a parking lot somewhere, while HPFP failure could mean sudden loss of power in traffic and being stuck on the side of the road. Also, the entire community seems to be on pins and needles to see if the N55 engine has the same issue.

Best of luck with your search.

For what it's worth, the HPFP warranty has been extended to 10 years/120k miles.

The pump replacements seem to be working very well.

Some N55 engines have had the problem, as you've mentioned, but luckily BMW has been covering them under the same N54 policy.
