As someone who just traded in my stinger and got the Supra... I can confidently say that Supra is on another realm of speed/power. Stingers are quick, especially tuned but they're levels to this and stingers aren't on that.
Very odd of that chap.
Not really answering op's question. But is it normal of this car getting a chit ton of attention? Seems so. I've had a stinger prior and use to get a compliment or interest once few months tops.
If I can add another here in Ontatio, Canada.

Got one today. 21 Premium in Red.
Traded in my stinger gt 2018.
Hardly drove to temp. I thought my stinger was getting some head turning moments but this car amps it to another league apparently.
