Two simple words to TS's question: Engineering and branding.
All the engineering put into manufacturing a continental car and a Japanese car is different. I would say every single cent paid for a more expensive continental car is worthed it if you can afford it. Everything is of a higher quality and of sounder engineering than Japanese saloons. The leather used to wrap the seats, for example, is factory-fitted for continental cars and locally fitted for most Japanese cars. This simply translates to good quality leather that lasts longer (factory-fitted) and lousier leather that feels PVC-ish and doesn't lasts as long (locally-fitted). And of course, the level of fit and finish in the interior is better for a continental car compared to a Japanese car. And quality of the plastics used in the interior is also better for a continental car.
Almost everything in most of continental cars are more well-engineered than Japanese/Korean/Malaysian/China cars. Engines are more well-engineered, suspension system more sophisticated, chassis more sophisticated as well and ergonomically, it's also better.
BUT of course, at the end of the day, it's the brand name that matters MOST.
Which will 'WOW!' more people? A Toyota/Honda/Kia/Hyundai, or a BMW/Mercedes/Audi/Jaguar? Obviously it's the latter.
But anyways, I also always see a Jaguar XJ8 parked at a HDB open-space carpark opposite my school, unused. Note that it's an XJ8, not XJ6; so this guy is actually quite rich. But why doesn't he drive it, it's a mystery. It's quite a badly maintained car. Scratches everywhere and the leaping Jaguar on his bonnet is gone!
