Jaguar is ok, Maserati is very expensive in maintenance cost.
- Audi A7/S7
- BMW series 6
- Acura RLX
- Genesis G90 (premium line by Hyundai, surprisingly great cars)
- Mercedes S-class (you can buy used one in your price range)
My impression - SV is full of show off, if you want to make an impression you should either drive something vintage, or simple and conservative, like Cadillac.
