I can only speak from experience when it comes to Evo's & anyone in RC Developments can back me up:

I've had 2 Evo's (VII & VIII) and they've both been in the garage more than on my drive at home! This is my 3rd Scooby now, the other 2 didn't have a single problem in their lifetime with me (and the P1 was tuned and did 24K in less than 6 months).

So in my experience, Scooby's are more reliable than Evo's and most other things on the road - as I've never had a problem with one (touch wood and lots of it as I speak)
