Mileage to expect from a used cassette.

Hello everyone,
I'm new to cycling and am planning to do a low to medium difficulty 400km trek and have come across a used Rockrider 5.0 for 50€ (approx $70). I've examined the quality of the bike (frame, tires, rims, bottom bracket, headset, dérailleur, etc) and found that it's in really good quality for such a price.
However, I've been wondering how many Km's to expect from its Shimano Alivio chainring set and the 8speed cassette. I'd be more than happy if you could help me with your opinion on this matter.
Thanks in advance!

You need a new chain. That one is too rusted. If you change the chain you might as well change the cassette as its unlikely to run smoothly on worn teeth.

AOwner clearly did not look after that bike, so god knows what the rest of it is like, I know you said it looks fine but still, the entire drive chain is gonna need replaceing,! I would not touch it with a barge poll myself!!!

Thanks a lot to both of you. Given the fact that I'm in a financially tough situation, would you recommend cleaning and lubing the chain?

The chainring looks OK to me. I'm not one who can tell by a photo whether the cassette has to be replaced but it doesn't appear worse than some I've ridden. It might have been just left out in the rain for a few months.

Why not just order a new 8-speed cassette and chain? They aren't expensive.

ps, I don't think anyone is going to recommend using that chain.

Cassette looks ok, but your new chain will wear faster running on it and 8 speed cassettes really don't cost that much. No, I wouldn't use that chain especially for a.tour.

Merci!!! Your advise is well taken. Cycling has become my new-found passion for adventure. I find it difficult to afford an MTB since I'm a student and am living on my own. My maximum is €150 for a used one. Anyway, this is my first time on Bikeforums.com and you've been very kind to answer such a small question. A big thank to everyone. Peace!!!

I could get 5000 miles out of that chain no problems.
