Yes, yes, I've submitted!
I don't normally do luxury cars, my preferred brand of obnoxiousness is a bit more, say, raw and visceral

But the main thing that drew me here was the fact that a) bigger engines = more prestige b) more cylinders = more prestige c) greater top speed = more prestige.
So naturally I put the biggest, gruntiest, most powerful engine I could into the car, without ruining its smoothness or reliability. Behold: The Sei* Emeritus, made by no specific company because no company I think imagine would bother making luxury cars!

Sporting a 6497cc oversquare naturally aspirated v8 which makes 563hp (Riso would be proud)... which pushes this barge to a top speed of past 300km/h (though you'll need about 5km of runway to achieve that)... and because I struggled to make the weight, I decided to make the car AWD, so it also does 0-62mph in under 4 seconds. On 235mm wide medium compound tyres. With an automatic transmission, making it the fastest damn auto this side of the millenium. It also hustles around the Airfield in 1:27.76, which puts it in the company of some serious sports coupes.
Yet for all its grunt and alarming hustle, the Emeritus holds a stately presence, its true performance belied only by the extreme exhausts and the hood feature (because the engine barely fits). With an all aluminium chassis, the finest of handcrafted interiors and sound systems, and stable, pliant hydropneumatic suspension system, you will be transported in a world of refinement, whether ferrying the corporate dream nuclear family of husband wife and two kids to the opera, or evading Papparazzi, police, assassins...
... or you could simply rock up to the parking lot knowing not only do you have a proper luxury car, you have the most powerful, fastest luxury car of the lot and suddenly your dick feels incredibly massive. Sei Emeritus, the whale of a compensation.
