Ford was good enough to provide a free bluetooth car kit to all Fiesta buyers in March, so I got my Nokia CK7W kit for free. It costs around 8.2K.
I have the ability to accept or reject calls, or dial the last number dialled from my mobile. But it does not have a caller id, so I generally accept the call and tell 'em to call later as I am driving.
Works fine with me. On highways however, I do talk on the bluetooth for long, depending on the urgency of the call.
The only hassle I've faced is calls from placement consultants when my colleagues are taking a ride in my car--I quickly tell 'em to call later
