Hi. I personally think you have picked 3 completley different cars that are no where near in the same category which makes choosin one out of them very hard. If price is not a matter then avoid the 350z. My personal pick is the RS4. It might not handle as well as the cayman but the power and practiacality of it is a great advantage. Having had a 350z its has a very low quality interior as compared to the other two and it is a bit on the heavy side. |
