I agree with this. Some dealerships will let you take a car overnight if they feel you are serious about buying. A local dealership gave my buddy a new IS350 for a whole weekend.

Very little cowl shake, especially when compared with my old Del Slow...

Still trying to figure out if the roll bars are considered rollover protection (if the answer is yes I will be taking it to the track)

Very happy with the roadster overall. It is fairly quiet with the top up even compared to the coupe.

Would buy it again...

I agree with above comments. I have a 370ZR, after having the 350ZR. I find the 370ZR "tighter" feeling than the 350ZR, and no cowl shake or feeling like it isn't rigid due to being a vert. Also, the upgraded top seems to produce a quieter interior with the top up, although there still is some degree of wind noise but it's very tame. Only complaint I guess I could voice is the mechanics of the top itself during up/down are "clunkier" than it was on the 350. I have no regrets thus far with my roadster purchase and love putting the top down every chance I get!
