DS2: Construction System Idea

I've been thinking about the differences between
high-tech and low-tech vehicles and finding a way to
make it matter "more" in game terms.

How about this: allow three versions of each chassis
size. Low, Mid and High Tech.

A Low Tech Chassis is a little cheaper, but loses two
capacity points.

A Mid Tech Chassis is just like those listed in the
book.

A High Tech Chassis is more expensive, but gains two
capacity points.

The differences reflect the miniaturization that
generally takes place as technology develops. There
would also be limits on powerplants and drive types
for each chassis.

I haven't worked out how this system should be costed,
it's just in the rough idea stage.

Any thoughts?
