The majority of the comments seem to be in regards to the Policar F1s, NSRs, and Thunderslots being superior cars. I think it is great idea to have some basically "stock" lower performance classes to pick from in our list of classes. As is currently the practice the classes will probably be raced on a rotating schedule, so not all of the classes have to be raced. The less popular classes can be skipped but they will still be listed in case there is a resurgence in popularity. With that said I think the Scalextric GT3 Class and the Carrera DTM Class fill that niche pretty well. Both brands can be purchased at reasonable cost.
Other comments are in reference to the Classic Sports Car Class, both Divisions I & II. I've felt these classes needed some restructuring for quite sometime now. From input I've received I would propose these changes to redefine the two divisions; Division one - sports cars manufactured through 1963 with 14K limit which would include the H&R Jackrabbit motor. NC1 and the BWA motors would also fall into this category. Division II - sports cars manufactured from 1964 through 1975 with a motor limit of 18k. All other rules pertaining to each class would remain the same.
I propose an F1 class based on the years or era that the current Policar F1 cars are modelled after. I'm not familiar enough on the years those cars were raced, so some help is needed here. With the class spec'd for cars of that era the Policars would probably be the logical choice but, if another brand of car fit the era it could also be raced even though it might not be the best choice (driver's choice as well as builders and tuners challenge).
That brings us to Thunderslots and NSRs. I propose to exempt these brands from all the other classes and form either one or two new classes for them. I don't know how well they compete against each other but if divided maybe another era designation could be used to separate them? From my experience on my old track the NSRs would pretty well keep up or beat anything, even the scratchbuilt cars so maybe these two classes could be somewhat of an unlimited class with nothing more than a max motor spec?
