The 8845 Dune Buggy was a Technic set of the 2nd series with independent rear suspension and new steering elements. This is a 4-wide model of it.
About this creation
The Dune Buggy was one of my favourite sets in the 80's. I modified it several times an even drew instructions for the modified models. Now I found a cool site about this model on technicopedia.com and decided to make a 4-wide version of this set.
Side view: The rear suspension is a little to high. The clamps just can't be postioned in the gap under the plate in LDD. In real LEGO this should work fine.
