A Good Buy?

Hi guys. I've been wanting to get myself my first ever car, especially a manual car. I'm 19 so my budget is very limited. Mostly interested in some mazda6' from the 2000s since that's what my budget will allow me. I live with Canadian Winters so rust will definitely be a common issue. This 2006 mazda6 S 3.0L V6 hatchback especially caught my eye and just want to get some input from you guys if whether or not this would be a good buy. Price might be a little high then what I'd like but I'm sure I can negotiate with the seller.

But anyways, thank you for your time and any bit of tips will definitely help :)
