learn a language in the car

[DudleySquires]

OH has started a new job recently that involves a lot of driving. She has also mentioned how she would like to learn a language. So I figured, what with xmas around the corner, it'd be a good opportunity to get some sort of language teaching CD for her to listen to while trundling along the motorway.

I've narrowed it down so far to Spanish Frnch or Italian (it's going to be a surprise present). Has anyone got any sort of experience with this sort of thing? Which product did you use and how did it go?
