Get a pre-owned VW Passat or Jetta, Audi A4, Mercedes C Class, or BMW 3 Series, ideally with AWD.
Sure your maintanace costs will be a little higher if you use a Franchised dealer, but if you used an independant garage specialising in your make of car it will probably be a bit less.
... & depreciation will probably be the same, and you'll have the benefit of owning a prestige desirable car etc etc.
