Bike was $300 when I got it, it's a Haro Backtrail X3.
It was left outside for 5 years all seasons. I believe the whole inside is rusted, based on a quick look up from the forks to the handlebars. I'm wondering if it's worth keeping and fixing or if I should just buy a new one. Money is not really an issue, I've got some saved up and I'd rather not spend money on fixing up this old bike if it won't be worth it. I also have another bike that's in the same condition with worse frame rust and a dent.
If I were to fix this, I think I'd probably need new bearings, a seat, brakes, rims and tires.
I'll upload some pictures in a moment, taking them now.
Pictures added! I can upload some more if needed, just ask.
