Imagine driving a very cool new car for a distance between 9 to 25 miles, getting out and then into another very cool car for another 9 to 25 mile leg and then repeating the same routine through 23 cars in a two day period.

Welcome to the 2010 NWAPA (Northwest Automotive Press Association) Run to the Sun held recently in western Washington.? After 23 cars and more than 450 miles of smiles, here are our quick impressions of the Nissan 370Z roadster.

Nissan?s only convertible, at least until they build a Murano convertible early next year, is the brand?s flagship of fun.? This solidly built roadster is pure sports car with excellent handling and performance pulling a 4.7-second 0 to 60 mph run and with a top speed capped at 155 mph. The most unique and exciting new feature is the six-speed SyncroRev Match manual transmission, which automatically simulates a sophisticated heal-and-toe downshift simply by pushing the transmission to a lower gear.? We can?t believe another model or company has started using this neat feature.? The Z? roadster, with a manual transmission, has a base price of $38,070 and $42,920 for the Touring model with a seven-speed automatic transmission.? The coupe version of the Z is about $6,000 less.
