fine if you intend to model a car park but not so good if you intend to model on roads and around the layout
I have just done a couple very quickly for demo purposes that are going to be used on my future layout
my intended victims are a ford escort xr3i and a vw transporter van

on most diecast cars manufacturing simplicity sees the diecast body shell riveted to the chassis so first job is to release by drilling with a mini drill

to split into component parts

if unsure of using or don't posses a mini drill , fear not , the vw transporter is a much easier single posidrive screw arrangement !

et voila !!

next pick your drivers/passengers mine are the old airfix/dapol figures cut down to fit ( you only see to the chest anyway ) ,,, also remember to make them appropriate to the vehicle ( a couple of builders would not be seen dead in a pink ford KA !! ) once figures are altered and painted glue in with superglue ( remembering to check headroom before commiting to glueing in and reassembly )

for the vw I painted the jackets dark blue to represent the typicaly early 80's builders donkey jackets and gave them hard hats , whilst not forgetting the compulsory builders van dashboard clutter !!

oxfords factory production process also sees un painted areas of black on window surrounds , whilst stripped down it would be rude not to run a little black or silver (depending on vehicle ) around to give a better finnish
before

and after

once done reasemle using superglue to hold the chassis back on if you had to drill out the rivets
