Before you switch to japanese and european cars, let me remind you that you will need new tools ( Metric tools ). Just some input since you have TC3 before ( Imperial ).
Best car in my opinion ( highest to lowest preference )
1. Tamiya TRF 415
2. XRay T1 FK
3. Yokomo MR4TC SD or Tamiya TB Evo4
If you want the car without hop up options........ drum rolls..... XRay T1 FK is the strongest and the most durable of all.
