And some twisties, as well as sitting in traffic.

I was told the US version is more luxuriously outfitted than the base Euro version - most of the US versions have leather, Euro base versions mostly plastic.
Light, nimble - the acceleration from the 1.7l 4 cylinder is surprising.
The car was still fairly new (just over 100 miles) so I didn't really go WOT for too long and didn't allow revs to get too high (though did touch 5500rpm, maybe even 6000 for a second or two...)
It's not a perfect car by any means but it achieves something Italian cars seem to achieve more consistently than German performance cars - actual quantitative performance figures and practicality aside, the 4C stirs the soul and gets into your heart and mind.
It was hard to keep the engine "on boost" (this may have been because the tranni would not allow us to put it into "dynamic mode" due to "break in" period) so there were lapses in the crazy acceleration (0-60mph in 4.1 sec, pretty impressive for a 1.7l 4 cylinder that can get 30 mpg on the freeway...)
The suspension was not as jarring or uncomfortable as I'd read (this one had the track suspension) and on smooth roads was downright comfortable (as would any car)
Ingress and egress was FAR easier than the (modern) Lotus Elise.
Handling and braking was...a revelation. Having been driving powerful cars well over 3500 pounds the last few decades (even track oriented Porsche GT3RS weighs in at 3000+ pounds) or underpowered but fun cars like the Fiat 500 Abarth, the 4C, especially with the non-power assisted steering, was just simply a joy.
I am seriously, seriously tempted...
