First/only post, I check here now and again.
To your question, I raced a full CCR season last year in a 430C. Was awesome, period.
Great series, and great people. Definitely "gentleman racing" (as in sane, clean), but very competitive and some incredibly quick drivers.
Would gauge as near/at the top of amateur ranks in terms of the level of seriousness of the drivers and teams, but very inclusive and approachable in the paddock.
JohnH set this up as a non-profit, so aside from the cost of the cars (any Ferrari Challenge car is expensive to prep, run, fix), it's as value-focused a series as you'll see. Emphasis is on fun, not complexity or politics. Teams like Universal Autosports are great at getting new people in, getting these cars out of garages and onto the track and supporting them with a good value proposition.
i believe Rob raced his 355C in 2011, as I recall he was pretty competitive. I met him at the Monticello weekend which helped me decide to enter the series. 355's and 360's obviously run among themselves, but it's fun to have a mix of cars. These cars are now "vintage racers" in many ways, so you'll see modifications to almost every car, for economy or reliability.
There is a CCR section on that other site.
I would encourage anyone who wants serious but fun racing to consider it; again, these are Ferrari race cars, so a step closer to higher level amateur racing vs. regional, but if you want to do it, it's a great place.
I believe 100% of the sponsorship funds go towards offsetting the direct series costs to keep entry fees low. A close friend is also a CCR sponsor and it has been a great platform for him to grow his business with that community. Met a lot of new friends.
I would have raced CCR again this year but had an opportunity to move in a different racing direction so the 430C and Porsche got traded. If I can ever justify getting a 430C again i'll be back.
