After offering relatively mild deal-sweeteners (cash, financing and lease) to Prius dealers and buyers, Toyota saw sales of the hybrid shoot up 74%. So for April, Toyota will offer Prius purchasers package upgrades such as stability control, upgraded audio systems and a backup camera. Depending on what package is chosen, the deal could be worth up to $2,000.

As we reported in February, Toyota's goal is to sell 150,000 Priuses in 2007, which is 44,000 more than in 2006. If they're already offering as much as $2,000 in upgrades in March, we wonder what to expect by November.
