How to know if this camera is not fake on eBay?

I want to buy a Nikon D3200 on eBay. I messaged the seller since his item was on tuition to see if he had any more and he said he did and I can buy it. He said that we can do it by PayPal, outside of eBay. I said can you make it an eBay listing and he said after this listing is done since eBay lets him only put one listing time by time.

I am looking through and the camera says Country / Region of Manufacture: United States. (Aren't nikons made in Thailand or he did not know and guessed US?)

Second, it says that the camera has manufacture warranty. So, is that a safe bet? Or can people just stick some serial code or something?

From 414 transactions, he has 98.8% positive feedback. He has been rated negative once from the person saying do not buy from this person but maybe that guy was easily ticked off.

What do you think?

DX lens effective focal length?

After understanding the difference between FX and DX and their pro's and con's now there's a new growing perplexity. What would be the focal length if a Nikon DX format 35mm prime is used with Nikon d7100. Will the focal length be the same 35mm or the added crop factor of 1.5x would covert it to a 52.5mm. Does crop factor apply to all Nikon DX format lenses?

Is the Nikon D3200 still a good DSLR?

Im looking to get my first DSLR. I was looking at the Nikon D3200 as it is good for both pictures and 1080p videos. I only really looked at Canon and Nikon as there probably the most well known for DLSR. The 600D doesn't have auto focus, I think the D3200 would be the best choice for me. The only thing that put me off it is the fact the it is a few years old. Is it still a good pick? Or is there something else in that €400- €500 price bracket that i have just not come across yet?
Added (1). I also looked at the Canon 100D and 1200D
