My one and only 'complaint' is that the top makes more noise than a regular hardtop. I asked about it during a service and they did something to it to help a bit, however, it still is quite noisy which, I guess, is par for the course for a vert!

 

My top has had the following problem: Intermittently, when the windows are up and the top down, driver's side window fails to go down before the roof goes up, causing a jam. Happened only once, but the only way to fix is to go to a dealership and have the computer re-set over the jam. I look out for the problem now.

Love my 2009 G37 vert. Drives great, with excellent power. Get the windscreen for the back seat. It's a nice touch. Not sure if it's standard or not.
