Which would be better to go with 1/24 or 1/32, for slot car racing?

Question

I am a beginner but would like to get into this competitively. But I also do not have a lot of money to spend.

Answer 1

1/24 seems to be the most popular. There will be only a slight difference in prices for cars and parts between sizes.  eBay currently has 6223 items listed for slot cars.  I have listed a number of sites that will give you more information and most have contact information where you can ask questions.
