This sounds good. As for the Mercedes 190E: the best version is called 190E 2.5-16 Evolution II. Only 502 cars were made. It will be good to have M3 Sport Evolution, Opel Lotus Omega ( or Vauxhall Lotus Carlton ) and Lancia Thema 8.32 there too. And do not forget Group B rally cars from 1982-1986. Each car was also made as road version for homologation. If you need more info about those cars, I can help you. I am collecting car brochures and have some about them. I will also have very good books about them in few weeks.
