Hyper 7 old model Hyper 8 newer model and Hyper 8.5 the latest model. Now would you rather have a 1999 1 to 1 car or a 2008? All the Hyper buggies are a good buggy just depends if you want the old version or the newer version. Yes the newer versions are better as far as up to date but all of them are very durable. For bashing and some club racing does not really matter. Now for serious racing it is a different story.
