I noticed a little differential noise in one of the cars we test drove.

Thanks to all for your input. I'll continue checking this post of more info as we continue our quest to find a nice car. Here in Tucson we don't have a real wide selection but we're not that far from Phoenix and we've even looked a little on SoCal. After New Years we'll get serious and hopefully be driving a CTS soon.

Thanks again,
Van
