4 and 8 I'm sure about (TT and Mini)... I think number 2 is a bit confusing. It's either a VW or an Audi
The first one I'm going to take a totally wild guess and say that it's a Porsche? It's only got 2 window buttons which means that it's either a Coupe or Cabrio... And that looks like nice quality so I'd say 911?
P.S. Notic, the fact that you knew which car the one with the seat is is amazing.
edit... just checked, definitely not 911... this is killing me!
