What do I need to know when buying a film slr camera off craigslist?

I love photography but don't know much about it or slr cameras, and I wanted to buy a cheap film camera to see if I can stick with it. I found a Nikon N6006 Film SLR Camera on craigslist for $40 and it comes with a Nikkor AF 35-80mm standard lens and some other accessories for free. I'm going to go check it out later today, but I was wondering what I need to look at to make sure it is working properly. Since it is a film camera and not digital, how will I know whether or not pictures will come out ok?

In any case of buying second-hand at long distance you basicvally have to trust the seller. Seeing that film-based cameras are now a specialist niche market you would want to know whether Craigslist has any photo equipment experts. Is that a general site or does it specialise in older photo equipment? If it is general then nobody there will know if the camera is good or not. My advice is to buy locally - you can shoot a test film, ask them to hold the camera while the film is processed.

If the manual is included you should check that it does everything it says it should. If the manual isn't there then beware - this setup is selling very cheap! Take a torch and check the lense for fungus. Take it off the camera and look through one end while torching through the other end at an angle.
The more you see the word 'auto' on a camera or a lense, the more there's to go wrong. The N6006 is a Nikon and they are a really top make, but it is possibly 20 years old. Age is not necessarily a bad thing but the older I buy, the simpler I want it.
A reasonably accurate shutter and a working light meter that needs easily obtainable batteries is all a camera needs to get you started. There are lots of well made screw mount cameras on eBay that might breakdown within a year but they come so cheap that b uying another is not a problem. There are 100s of fully working screw mount (M42 lense fitting) Praktica/Chinon CS&CX/Zenith bodies selling literally for a dollar or two. Prakticas and Chinons take the PX625/LR9 battery that you can get anywhere. Most Xeniths are a bit limited in facilities and have external meters that do not need batteries. These cameras only need batteries for the meters - everything else is mechanical.
M42 50mm standard lenses are rising in price because they can be eaily adapted to dSLRs but cheaper zoom lenses in the range you mention can be picked up for under $20 - I see a 35-70mm selling for $10.50! Post and packing costs need to be added to these prices. If you see a Zenith in a thrift shop check it out - even if the camera is poor, the Helios lense on most of these is a really great performer!
