The best car was quite possibly my Tamiya TA05 with a twin deck chassis conversion and trf arm mounts.
A little heavy but man it was a tank! You could throw literally anything at it and it was competitive in its day.
My current t4 13 is also very durable though
Worst - probably the tenth technology predator. or the Kyosho mid optima pro turbo.
Both cars broke just looking at them.
