Honestly, as I'm in my 40's and remember what things were like before the Internet, I don't think I'd miss the Internet that much.. probably be better for my health as well.
I only miss the car when i want to go out of town. i've never missed my cell phone, one time ever..ever... ever.
That said, I would still rather keep my Internet than gain a car. Safeway delivers for free, I no longer need to go to Blockbuster to get new content, and I can (if I chose) work completely remotely.
Living without a car sucks, especially in California where public transportation is a joke, but its still better than living without internet.
