I am new to slot car racing and I don't even know if this is the correct place to post this topic, so please bear with me.
I 've recently bought some Scalextric analogue models on eBay and would like to convert them to digital. I 've read some of the relevant topics on this forum and found some very useful information. However, and this may sound daft, I am not quite sure which chip (i.e. saloon (C7006) or single seater (C7005)) to use. So, I would appreciate any help from the more experienced forum members.
Here are photos of all the cars in question (apologies for the images' large size and the fact that some models appear more than once).
Car 1 - Ford Focus
Car 2 - Ford Focus
Car 3 - Ford Focus
Car 4 - Subaru Impreza
Car 5 - Jaguar
Car 6 - Jaguar
Car 7 - Porche
Car 8 - Porche
Car 9 - Mercedes
Car 10 - ???
