I have 4 varieties of each body style (x4 sedan, x4 SUV & x4 compact) that I build in equal quantities.
E.g. one of my chassis’ running order is:
Sedan 1 - All universal features included only (+10% sale commission)
Sedan 2 - All universal and common features included only (+20% sale commission)
Sedan 3 - All universal, common and rare features included only (+30% sale commission)
Sedan 4 - All universal, common, rare and very rare features included (+40% sale commission)
The above is the same for the SUV and Compact styles equally shared on 6 chassis/body lines
With 4 exports running at full tilt (I can’t get the exact output figure right now, I’m at work) my showroom figure usually averages around the 14-20 cars at any one time. 600 is mighty impressive! Get them sold, and a Brucey bonus of around £12M± is coming your way!
Be sure to follow up on rival competition notifications and update your models features accordingly.
At the minute it’s a stab in the dark on what the market wants but the above appears to work okay.
[EDIT] The latest release (1.25) should help with the requirements of the market and market share, see Cliff’s update/developer blogs.
