They can be prone to a leaky seal at the back of the transmission which requires the transmission to be partially dropped to get to. Mine was fixed under warranty, and I suspect most that were going to have an issue would have had it by now and been fixed, but worth checking the service records for. Everything else should be pretty good, just look for shock wear. I replaced mine at 75km. Oh, and they DO respond really well to a remap - you will release 50-60Nm, improve fuel economy, and most importantly throttle response.
