Love my 02 Sable Wagon can I still get a newer model of it and where would I look?

I like the car because it's good on gas and has room for what I need but, mine is having issues because of age. So many fixes are killing my wallet. Can I find one younger? Has Ford stopped making Mercury Sable Wagons and if they have which vehicle would give me the same room, be five years old and wouldn't kill me at the gas pump????
