The aging Regal is an acceptable car, but doesn't match up to its more advanced competition. Drawbacks include ungainly handling (the optional Gran Touring suspension improves that somewhat) and front seats that become less comfortable the longer you sit in them. On the plus side, the Regal rides well at lower speeds, has a quiet cabin, and features a smooth-shifting transmission. It's been a very reliable vehicle.
