Hi,
The Kyosho is a good car, but is a old one now.
You can also make your choice around Capricorn, Serpent 733, Velox10, and you still have the Xray NT1.
All cars are good, but you must choose also with the easier way to get spare parts, set up...
I have a Serpent 733, and it's a really good car. In my local track (France) there are many Kyosho and Xray. Many of them are changing for Capricorn and Serpent.
It's not easy, try to get the advanteges and inconvienience of all of them to make your choice, and have a look on the price of the spare parts
