When looking for an RC car i think you've got to look at stock avaibility. All very well choosing the car with the pretty bits on it and the big motor but you need to be able to buy the spares and with the recent closure of Ansmann Racing spares are going to start to dissapear out of shops.
Id have an RC8.2 purely the fact that the cars are so robust and easy to maintain but also look fantastic
Such a fantastic car for the money you'll spend aswell!
