Doesn't look like it's had much care and attention does it? Tyres look oversize, which suggests the previous owner didn't have much knowledge, may be why it's been down the road. So, you replace those, replace chain kit (chain looks well rusty), what else hasn't he cared about? rusty/corroded nuts and bolts will be a pain every time you need to remove something, so where else has that corrosion gone? Hasn't seen a bucket and sponge in a long while, assume from this that it hasn't been regularly serviced, so problems just piling up. No, one to avoid, seems cheap, good reason for it, not cheap enough, you'll end up laying out far more.
