A few weeks ago, navyeagleeye86 introduced the Private Eyes series of Micro Machines.
These step vans, aka bread vans, are also from that series. They are quite literally boxes on wheels.
The Dog Catcher is from my childhood collection, while Porta Pets came from a recent HWEP with R32Rennsport and TFritch.
I presume Porta Pet is a mobile grooming service.
Interestingly, these share the same inner picture. That picture makes perfect sense for a dog catcher, not so much for a mobile grooming service.
