Check what categorie/ chassis/ motor etc... that is used in your club.
For the chassis, think of availability of parts and cost, one of the reason I run Asso TC6 is parts are cheap and plentiful even in Europe or far East.
Make sure to get a "Lipo" chassis so that you do not need to work the car balance too much.
Depending on motor class in club, buy the appropriate speedo, but if you run standard classes (10.5, 13.5, 17.5) and your speedo cannot take motors lower than 8t be careful not to go mod after or you will blow the unit.
Again ask in your club, this is the safest route.
