Our cars probably catch a lot of negative feedback in the UK because of Clarkson's review on Top Gear eight years ago. No offense to the British, but they seem to have an abstract type of love for anything British, even if it's rubbish. Anything the Americans produce is, well, rubbish... even if it's brilliant.
Also, most "gear-heads" simply assume that since the car is based on the R170 (a hair-dresser's car), the Crossfire will be equally boring.
Here in the 'States, it's a bit different but it all depends on where you go. I didn't get many second-glances in Atlanta last weekend, but they're accustomed to seeing Lamborghinis on a daily basis.
In my home town, it gets decent feedback. Lots of double-takes, gas-pump interrogations, etc... In very rural communities, people look at you like you're driving a full-blown exotic.
Haters of the car exist in every locale. These are normally the people driving every-day sedans and commuter cars, yet because they read that "some car is faster around ___ racetrack, clearly the Crossfire can't be taken seriously and is only good for scrap metal."
I allow them to think that, while I ignore them and blow their doors off.
Same thing at the race tracks. Virtually NO interest is given until the almighty Corvette, Mustang, Camaro all get schooled by a lightly modded SRT-6. Then you suddenly have folks around your engine bay with this
"forgive us, we knew not what we did" expression on their faces.
I don't really concern myself with the opinions of others... if you drove a Ferrari, there would always be some broke kid saying "should've bought a Lambo". I ignore the haters, and express gratitude to the admirers.
