Sadly, the owner of SG Motorsports, Stephen Goodyear, passed away in January at the too-young age of 52 years. Another member here found a short obituary paragraph on Ivan's own website lamenting the loss of our friend.
I assume that at some point Ivan will look to appoint another agent for his products in the UK and Europe. In the meantime, I suggest that you contact Ivan direct to see if he can supply what you need direct.
RIP, Stephen. You were a great guy to deal with and much more than just a business associate.
