Sounds and looks like a really nice 3g, that. And a good price.
Just bear in mind though, if you want to use that as a daily runner in London, over speed bumps etc. parts like the suspension bushes will either already be knackered on it (they all are getting that way, due to age now unfortunately) or will be on the verge and will die quite quickly.
Perfectly fixable, but they are very difficult to get hold of now, so you may end up forking out for polybushing as the only option and the kit for a 3g isn't cheap.
