Selling my Cars (Customer customization)

Would be nice if i can Only can Make an Platform and my Virtual Customer can customize his new Car at the Dealer.
So i build an Platform/Default Model and mark Engines and Options (Standard Heater,AC, Automatic AC, Cassete Radio/CD Radio and so on) which are also available on this Platform. Than i can Set the upcharge for each.
Example my Default Model from this Platform costs 22.000€ with the 1.4L Enginge and Standard Heater. So i can set a upcharge for AC(500€) and the 2.0L Engine(1.000€)
So my virtual Customer buys this Car with this Options so my costs 23.500€.
So i have Only one Default Car/Model to Build. And let the Customer Decide which Options he want.
And than i can make Special Models of this Car. Like the Same Car but with an Special 3.0L Engine which must have an Special Front for the Cooling.
Would also be nice if i can Build Packages for the Options and Name these Packages.
Like Active, Sports, Aero...
Example the Sports Package has an 2,0L Engine included+CD Radio+AC and Costs only 23.000€ so it is cheaper than Customer customization.
The Active Variant has an 1,4L Engine and Cassette Radio and Standard Heater.
So my Virtual Customer can decide if he Takes customised Car where he Pays for every Option. Or he Takes this Car with an Package.
