Cool to seriously uncool in 5 seconds
I think it's quite cool as I only saw my first one on the road last week.
However, I do think the materials lack quality for longevity (that's true of most cars these days) and when they become common enough to have bad drivers (ignorant, uncourteous or simply those with zero ability) behind the wheel then the rating drops.
The level of technology in luxury cars these days also means they are environmentally unfriendly judging by the ever growing number of cars where parts supply is only supported for 5 years. In that respect, I think we will catch up with the Netherlands where expensive cars are virtually looked down upon. It took me years to understand that emerging attitude. It appears to be environmentally driven and that means the Stinger will become seriously uncool in just a few years which is a shame but indicative of the non enthusiast social climate and heralds entry to the new distopian world order.
