To follow up Jesper's beautiful Puma (if that's an appropriate word for this pugnacious looking vehicle) here are some photos of my Puma virtually complete and replete in its original Matchbox two colour scheme. The dark grey / light grey is quite subtle and works quite well. Shame I suppose that they would all have been in dark yellow, but never mind - it kind of makes it look like a black and white photo.
The reason I was interested in the Panzer Lehr insignia is that the decals in the Matchbox kit don't include that; have they changed for the Revell version? Matchbox options are the SS Hohenstaufen number 1111 - a vehicle captured in Normandy I think and very commonly reproduced in photos, or XI Freiwilligen (?) Panzergrenadier Division number 125.
Following Jesper's comment on inaccuracies, I took some quick measurements, and my rough calcs made the length and width come out at about 1/75 or so, the turret came out more like 1/85, confirming what he said, although I have to say, I wouldn't have noticed just from looking at it! As for the wheels, I had them come out at 1/71, again confirming Jesper's comment.
In the Matchbox instructions they seem to show the exhaust mufflers being put on side ways, as I think Jesper has done; then in the side views for the paint scheme they show them the other way. with the curved edge top and bottom rather than sides. Anyway, looking at photos they are not the right shape in any case! The 1111 vehicle they may have based it on seems to have lost it mufflers, so maybe that didn't help.
Anyway, here are the pics, note the wheels and soldiers are all held up with BluTac, as I'm planning to paint the tyres separately, hence they look a bit wobbly.
