I want to get a out door rc car for my son one of the good ones whit the trigger remote my budget is £200

the testarossa is an outdated car. a lot of its technology has been replaced with much better systems. a testarossa when new produced less than 400 hp. street racing cars often exceed 600 hp. (some even go as high as 2000 horsepower)
on top of this, technological advances in materials and chassis deign has made cars very strong and very good at handling.

if you go to an illegal street racing meet with a testarossa, chances are you will lose.
