I have a Nissan Sentra 2007, 118k. It is well maintained (consistent checks at the Nissan shop), well, as much as possible assuming integrity of the shop. I am not a mechanic myself unfortunately. I went back to school and car was sitting in the parking lot of my building for the past 12 months. I took it for a drive 4-5 times, but otherwise it has been sitting idle. My question: what can dry out (like rubber, etc) or can get damaged otherwise in the idle car? This is probably a very broad question, and I know forum's policy about broad questions. If it is, I will delete or if you can help me rephrase the question, that would be great. I am planning a ~1500 km road trip (that's total) and will definitely service the car beforehand.
The car: - has the battery disconnected for the entire idle period; - is stored in a not very dry, not very humid basement parking area with good airflow; - was serviced 2000 km before putting it in "idle mode".
Again, for real solid answer you would need way more details, but is there something that is very obvious that one should be aware of?
One thing I had a "problem" with is a squeaky belt on colder or rainy days (I am in Vancouver, Canada and it really rains here :)). It stops squeaking after 20-30 seconds after the start up, but I thought I'd mention. I wonder if that was more affected by staying idle.
