Well, I didn't do it to
mine, but I did make the pilgrimage...
Rented a brand-new GT86 and did four laps at the Nurburgring! I was their first customer in the car - it only had 180 or so miles on it. What a blast.
Obviously it's not quite a fair comparison. This has had the interior mostly stripped, a cage bolted in, sticky tires and track pads, but I can attest to the traction-control being much more useful in the '17 vs the older models. I didn't even use track mode (b/c I didn't feel like spending my $6000 deductible), but even with all the nannies on it only really got upset by the carousel. I feel like the clutch and shifter were also a little better.
I may still not care for the front end, but man, such a great drive in a great car!
My best time "Bridge to Gantry" was my second lap at 9:40 with one yellow flag out on the track. By the time I got to my third and fourth laps there were four different cautions, so they were slower over all.
