From a sponsorship perspective.... its hard to pick a single major automaker that isn't suffering right now because of the economic downturn.
Since GM and Chrysler took bailout $$ and are now asking for more, I am sure they are trying to get out of as many of their indirect sponsorships as possible. Especially the way Congress has been pouring over and publicly lambasting what they deem as frivolous spending of taxpayer bailout money. In the grand scheme of things, a $1 million/year sponsorship for GM is not that much.
Toyota is not quite as hip as it once was some years ago, with the exception being the Prius. Its sedans have gotten ho-hum reviews as of late... even when given hybrid technology, that only increased the Camry's MPG stats by a marginal %.
If you are looking for something other than Honday, I'd offer up Ford as a possible sponsor. Quality has greatly improved since the early 90's and the Fusion has generated a lot of popularity. Now with the 2010 models just announced, it might be a good wave to jump on. The 2010 Fusion Hybrid will be incorporating a better fuel-saving technology than Toyota, GM or Honda can offer at this time. The Taurus has undergone a 3 year complete makeover for the 2010 model year, with a ton of gadgets and technology that rival many luxury car makers. Its styling has borrowed from the lines of its European counterparts.
No I am not an employee or linked to Ford other than my 1999 Taurus that I own. I was just very impressed by their offerings at the Detroit and Washnington DC auto shows this year, and think they are turning a corner to provide a greater product than they ever have. Will it actually happen, I don't know and won't bet on it.
Another plus is they are not taking Government bailout money.
Downside is their sales are on the rocks, like everyone else.
Anyways... just my opinion.
