Summer madness is here. Car companies from Kia Canada to General Motors of Canada are rolling out aggressive sales sweeteners just about the time Canadians start heading out for vacation.

The idea, of course, is to keep showroom traffic moving at a time when most of us are thinking about boating, golfing, barbequing and loafing - but not spending money on a new ride.

Kia's promotion is called the Summer Sale event. It's all about moving leftover 2010 models from dealer lots.

"The core of this clear-out program includes 0.0 per cent financing on all 2010 models, no payments until the fall, plus cash savings up to $7,000," says Kia.

Last week, GM of Canada and Ford of Canada once again revisited what has become the annual "employee pricing" promotion. Basically, that means buyers pay dealer invoice for a long list of new Ford, Lincoln and GM products.

As my Globe colleague Greg Keenan reports, "The employee pricing program, which has been offered by GM and other auto makers in Canada in past incentive wars, will be offered until Aug. 31, and GM will be joined by Ford Motor Co. of Canada Ltd."

Interestingly, Chrysler Canada has not yet fired up an employee pricing program, but it's only July. Instead, Chrysler remains quite aggressive with cash incentives.

Here's a look at four deals that represent some of the summer madness happening out there. As usual, pricing information has been provided by carcostcanada.com.
