I'm well aware that both cars are the brainchild of Jeremy Phillips as my Striker was a Sylva car rather than a later Raw model.
I drove a Mojo on the road and I found the driving position a little strange although it must be said that was the ONLY Mojo I drove and the handling and driving characteristics might have been down to the suspension/tyres and general set up of that particular car. Also, compared to the Striker the overall feedback I got from the Sylva Forum that I subscribed to while I had my car was that the Mojo wasn't fantastic on a track and certainly nothing like a Striker.
That said, if I was to choose between the two as a daily driver I would go for the Mojo as the simple practicalities of getting in and out are much easier in that than in a Striker.
