E-Series Mod V2

Hey Guys,
I'm looking into re-vamping the E-Series Flash game that i created a while ago.
I'm after ideas on how i can expand it to suit a majority of people.
I'll likely expand it to include
EA-BF
LWB Models
Wagons
I've learnt a lot since i created the last version that means i should be able to create it to include many more options.
I'd like input on what YOU want from it?
