Nasa isn't great for beginners as they put a ton of cars on the track at once and aren't the best with their safety record. I love them for advanced drivers and they are cheap but track time is limited and, again, lots of cars on the track at once. Instruction ok.
Hooked on Driving is ridiculously expensive for a day of riving and I all I can see is that they buy you lunch.Instruction is ok.
Trackmasters is low key and priced fairly with a good amount o track time. Instruction is hit or miss. I like them the best.
