Make is largely irrelevant IMO.
Much more important is where you are racing, what cars do they run and what does the local shop stock (spares).
All the main makes are fast, robust and handle well. They all cost several hundred to buy and kit out.
There are always the latest fads and currently it seems to be XRay and Schumacher K1 as they are the most recent. You will find posts saying every single car out there is the best but your ability is 99% of the equation so pick any of them from this list and you will be fine.
