If I remember correctly mine came out at 680kg
That is with a full tank of fuel 35ltrs
I used 2mm thick tubing on the chassis, and didn't realy have any
thoughts on weight saving.
So at 680kg I'm quite happy.
Mind you when I sit in it the weight goes up a bit,
I could probably make 2 of Andy
The car still goes liks sh1t of a shiny shovel.....
