I was surfing the Grinning Shull site, and see he has discovered a £1 pack of Poundland cars that are "close" to 1/150 or 10mm.
Burning rubber Micro Racers although they appear under other Micro titles as the Chinese suppliers knock them oot.
I looked at a few of them - they are Micro Machine ripoffs. When I used Micro Machines, I toned down the paint and sandpapered the tyres down to scale - and filed away spoilers etc. The police car, the salon and the 4x4 all have potential.
The worst can supplement a street barricade as burnt out wrecks and the best - at £1 for 12 - with a paint job will do nicely.
