I've heard that the early cars had weak half-shafts, but they were replaced on my car with "heavy duty" units before I got it. I keep the CV joints and Quaife differential well lubed (my car is chain drive, unlike later Radicals) and have had no driveline trouble. I've had no issues with the steering or suspension or Wilwood brakes; I use PF1 pads and they wear like iron. I recently rebuilt my Penske shocks (many $$$ with no noticeable effect). I inspect the hubs and frame regularly and nut and bolt regularly. The only issue I've had is two of the frame rails around the engine (Rilltech '08 GSXR, solid mounted) have cracked and I've had to reinforce and reweld them. And the bodywork is FAR from lovely; cracks, chips, breaks, etc. But compared to what I regularly read on ApexSpeed and the DSR Forum, I'd rate my Radical as reliable and easy to maintain. And I can single-hand it at the track; no pit crew. All that said, it's not a Toyota sedan.
