Websites listing car specifications and equipment levels?

[FreeLitres]

I'm looking into my next car which I will have to get in April next year.

Does anyone know of a website that lists trim levels and which equipment they have as standard on new-ish cars around 2008-2010 vintage?

For example, which trim level has aircon as standard?

Thanks
