The Counterlane cars are re-issues of the Powertrack Plus cars. Broadly speaking, Dapol had significant 12V chassis stock and where possible supplied these cars with the 12v sets.
The 6v Race & Chase set came with the 6v police car from PT-6000. The pursuit car must have been fairly random and possibly explains the existence of various Counterlane 6v cars out there. The red escort, green Saab and white Jaguar are such examples.
As for the 12v cars, it's business as usual but I suppose the biggest surprise is what cars are not featured in the line up. The Stingray (PP-141), Fiat (PP-142), VW (PP-140), Escort (PP-143), Saab (PP-139) for starters. Bizarrely, the Bandag Bandit is not included either, but the Super Boss is titled as the 'Tyrone Bandag Bandit'.
Yes, I know the Saab (PP-139) has appeared on ebay this year in a Counterlane box. However, I have to at least keep things factual and clearly the Saab could have been a Powertrack Plus car that got thrown in a Counterlane box by a collector. Such is the limited availability of this Saab it is early days to conclude its origin.
One other thing to notice on the Dapol cars is the other stated 6V car is the orange & yellow BMW. This could suggest Matchbox had produced several stocks of European PT-6100 sets before their eventual collapse.
