I have an idea for the Navigator. Lincoln, like LR with the Range Rover, should built the next one on a aluminum platform. Yes the cost would go up, but the handling and performance would greatly improve. The weight would be reduced and gas mileage would go up. This would also differ it from the Expedition, something which has plaged it for years. It would heighten Lincoln to be a real player in the Luxury market, which the buyers of which have not flocked to Lincoln in a dozen years.
