A massive update here.
I did the following batches each day since the last post. Tomorrow will wrap up the final R cars, and then I'll probably power through the remainder some point next week. I don't have reviews for them quite yet, but I'll work on it. The Honda RA300 and the racing 300ZX are updates to my previous, very slow times.
