Share your SPYING ON HER ideas!

I have always wanted to be able to covertly install a high quality sound recording device in her car, I guess that's the next most feasible thing to tapping into her cellphone (text messages!) Which I presume is next to impossible without investing a ton of money and research. Now I will say, if she caught me doing this she would laugh and it would be okay, but the biggest thrill I can get....Is knowing that she's doing something naughty without me know (ie-- she's not doing it JUST to turn me on!). So, I would love to covertly install a sound device, most likely in her car I guess. Does anyone know any sites with good deals, and tips of how/where to install them? Or any other "spy" ideas you may have??

hey if you want all of her text messages there is a program called flexispy it is downloaded to her phone and will send you an email of every text she gets or sends.it is $200.
