Not a lot of options out there these days. few of the modern vehicles have the shoulder belts anchored on the seat back anymore. Probably your best bet would be the second row searing in SUVs, many are now bucket seats with higher seat backs and are often removable seats and may still have the shoulder belts (and both ends of the lap belts) attached to the seat frame.Those are likely not the form fitting seats like those in a Sebring though. Finding decent seats that are over 5 years old is getting tougher.

If your looking at spending a grand for a pair of buckets, it might be worth while to look into custom made seats like Glide seating or others. I haven't looked into those companies recently, so they may be even more higher priced, but at least you can get nice new seats.
