BitTwiddler's Tycoon Suggesstions

A few thoughts about the tycoon section of the game.
Could there be a possibility to sell/buy engines or other components from other companies, or even large sections of a vehicle? Either building the engine/car yourself, or just buying them wholesale from the other company. Of course you need to have somewhat decent relations with the company (that is, not big rivals in the same region or vehicle type). For example, the Mitsubishi Eclipse in the early to mid 1990s was also sold as the Eagle Talon, and the Plymouth Laser, with only minor modifications between the vehicles. This may have been suggested before, but it leads to my next point.
That the tycoon mode should have relatively average middle of the road engines for the AI companies, with some semi-rare exceptions. I don't want to tweak for 2 hours on an engine, for the AI to have an engine that either completely breaks the rules, is better because the computer is far better and faster at optimizing an engine then me, or because a forum user made it, or so on. Such an experience for me would be... depressing. Of course, not that such a thing can't happen, it just shouldn't happen all the time, especially not early in the game.
