Flat Towing Buick Regal?

We're looking for a newer car that can be flat towed. We definitely want something comfortable. We used to have a Buick Regal and loved it, but never towed it. We are wanting that size car and found a 2014 we really like, but told it can't be flat towed. At this point we're looking for cars to check out that might fit our needs. If your flat towing a car you love please let us know. We will be driving this car a lot besides towing it. Comfort is important!!
