I hate to spoil the excitement, but the kit need a lot of attention to build a decent model. For all modellers interested, I recommend getting the excellent Photo-CD`s released by Modellbau-Koenig shop:
http://www.modellbau-koenig.de/Literature/DVDs/Referenz-Foto_CD_Boxer_sgSanKfz_A1_i295_48642_0.htm First, the decal version with the Boxer dog symbol is the A1 version while the box despicts the A0 version. The main difference betwen A0 and A1 is the reversible Red Cross plates, one more camera on the roof and the mine protection plate under the hull. If you compare the boxart with the kit parts, you will notice that some details that are recessed on the real one are raised on the kit. These are unneccessary mistakes and take some effort to correct.
As usual, RoG kits are intended for "average" modellers, with the emphasis on being "cheap" for the sake of details.
P.S.
Building an interior in the model would prove twice difficult since modern German vehicle have VERY complex interiors and are still cramped.
