Thanks for the link to your track, it looks like Friday's are the highest turnout where most folks only run 1 class, and the most popular class in your area is 17.5T 2WD Stock Buggy. That's probably going to be the best class for you to get started in.

I see they posted a link to their RCTech thread here:

That thread has tons of useful information and appears to be relatively current. It appears they recently switched from clay to turf and ProLine Z3 Pyramids are the most popular tire at your club.

Our club recently did the same and I can say that the single best car for turf at our track is the XRay XB2 2018.... very important to note that there are earlier versions of this car , typically 1 release per year with the year as part of the version number. If your track doesn't carry XRay parts then don't bother running this car... chances are most are running Associated or Losi based on some track photos I've seen on their Facebook page.

If money is tight, then I think the B6 would be a very decent middle of the road kit to get, though not sure who has them in stock right now:

It's very important that you get the turf/carpet edition and don't get the clay/dirt edition, they are worlds apart and it will be very expensive to convert over to the other surface type.

Best of luck!
