That James Bond car was a thing of beauty. The gold one, if fully working with a decent box, you can expect to pay £150 - £200 now. The silver ones are worth a bit too. Corgi recently re-released both, once again the gold coloured one is rarer and is expected to become more valuable.
Ah yes, the Batmobile, I had one of those as a child. There are a lot of "playworn" ones about that aren't worth much. The missiles go missing, and the front windows are very breakable. A boxed one in nice condition you can expect to pay over £200. The prize pig is the Batmobile / Batboat set. If you find a boxed one and it's under £500, you've done well.
