Yamaha R1, with the stock exhaust in place for street riding, a fairly quite Suomy helmet, and I wear earplugs of course.
My weekend ski trip mobile/grocery/kid hauler is a Mercedes wagon. Good for hauling audio gear, too. Self leveling rear suspension can handle the weight of coffin sized loudspeakers, and giant tube amps.
Soon to be purchased car is a Nissan 350z, because I think the 370z looks like a catfish, and I'm cheap. But I'm also considering a low mile E46 M3, or a Porsche Cayman...but that will take away from the new motorcycle budget, tire budget, engine budget, track rental budget, skiing budget, and of course, audio equipment and record budget.
