Greg:
I suggest Artista; their figures are realistically posed and nicely painted. They will custom-make figures to order; like you standing at a BBQ grill; i.e., posed as if you are preparing steaks for dinner.
At 1:48 scale, a 6 feet tall person should be rendered as a figure 1-1/2 inches tall.
As for vehicles, go to DIECAST Direct on the web. They offer many brands in their catalog - cheap vehicles from China and pricey cars by BROOKLYN.
Carry on, regardless ....
