Aside from the wheel arches and front grille, they appear to be the same vehicle.
Was one built under liscence from the other and sharing mechanicles, or is it just an example of coincidental parallel engineering?
The hornet is quite a bit bigger than a marina, completely different design, and with the Marina you run the risk of a piano being dropped on your car. That never happens to a Hornet that I’m aware of.
Only if you’re James May. Richard Hammond had a piano pre-positioned on the roof only as a preventive measure
That said, a lot of sedans from around the turn of this century (and heck, even up to today) look similar (Asian, European, N. American, etc) due to coalescing around a standard rounded aerodynamic shape (think it’s call the teardrop shape, used to be called jellybean shape when the Ford Taurus more or less introduced it way back when), so much that without looking at the grill/front end of a given vehicle it was hard to determine what company manufactured it. At one model year, the rear ends of a Jaguar and a Hyundai looked frightening similar.
Made me chuckle at commercials back then featuring owners of such cars (?Mercedes ? BMW? Audi? Lexus? don’t remember), who would re-position mirrors or Security cameras or whatever to gaze at their generic shaped vehicles all day - hey buddy, you don’t own a Plymouth Prowler or Retro Ford T-Bird or Chevy SSR or any other vehicle that at least looks unique, regardless of the performance…
