Ha ha, an SD based buggy brings back memories.
Here's the one i raced in the 2004 Nats and Euros.

Was a great car and performed well. Was a shame I had to stop running it. It just needed a couple of bespoke alloy pieces manufactured and a bit of £££ put in to the project.
Was ahead of it's time with the 3x3 cells and B4 slipper.
