Welcome.
You should start by trying to learn as much about the cars as possible, or if you're in a hurry, find someone who knows lots about these cars to hold your hand. There have been many posts like yours, so judicious use of the search engine will pay dividends.
The car you posted is pretty. But it seems expensive. For that kind of money, though, I'd want a correct fuel cap and a correct engine bay (hoses, clips, etc). Other than skin deep beauty, though, (and she's a looker) these photos show very little. You'd need to see the underside, sills, etc, although I imagine that if she's been restored as is stated, it should be fine. But I think it's over-priced and that the engine bay restoration is a bit sloppy. (Take a look at the brake reservoir, for example). It almost looks as though it's had the Silchester treatment...
Good luck with your search.
