Thanks guys...
It meaures just over 42cms in length, so yeah it's huge!!
Colour wise I haven't decided just yet, it's actually a refridgerated box lorry but I'm thinking about cutting that down and converting it into a car transporter/breakdown truck and yes it's 1/24th scale so it should look alright with the other Tamiya kits!!
$95!! that's Aus$ I take it? This kit was in my local shop and had been reduced down from £29.99 to £24.99, not sure what that is in Aus$, he also had an Italeri Subaru wrc Team truck which is an articulated (I think you guys call them semi's?) but you also get the Impreza Rally car in the box but it was £49.99 so I had to give it a miss.
