I have owned 1993 & 1996 Q45. The 2006 Q45s ride is exemplary and far superior to the others. The vehicle allows you to feel the road like a real sports car and yet, ridding in luxury. NOT EVERYONE HAS ONE! Mileage not bad for a V8,340hp. Design allows the car to speed up without wind noise. To bad 2007 will not see one; however, I am told that in 2008 the Q is coming back with a vengeance.
Design, reliability, materials, dealership customer service A+ (including service manager)
More color choices and interior combinations, higher horse power, being able to choose suspension (sporty/luxury)from inside cabin, A/C vented seats.
