I bought mine before there was any talk of changing to the all red interior and I have to admit was quiet concerned even after I saw some photo's. But after viewing the car in person I wouldn't want anything else. The all red sets it off nicely and does give it that classic sports car look IMHO.
I don't think it's fair to vote one way or the other unless you have had a really good chance to sit in and drive both. It seems everyone that has posted about liking the all red initially didn't like it until they saw it in person.

 

I reckon it looks sweet. So does the blue interior. My preference is for these solid colours (with the more subtle black accents) as opposed to the previous two colour combinations, but that's just me.

 

I love my all red interior.

 

All red all day!
