yes, yes... with the roof down, after 3000rpm, you've got extasy: 6 cylinders, alfa muffler and turbo whining.... if you enter a tunnel, then.....
concerning the hardtop, i am not sure about the alfa one. I have some official pictures of it, and it doesn't blend as nicely as the weissman one. the alfa one has two wings which cover the sides of the car up to the descending side line... so you have a 2cm layer on top of your car on the sides. Plus the price, 3500euros instead of 2000.
BTW, have you tried the hardtop? is it really worth it (noise wise in winter)?
I will post pictures soon.
