Last night I drove the Z with the top down and it was 50 degrees out! In the past I have never been comfortable (in other convertibles) under about 55-60, but surprisingly enough 50 was quite comfortable!

Maybe it's the wind screen, maybe the fact it's a 2-seater...I don't know...

My question is, fellow Z3 owners, what is the coldest temp you'll drive with the top down?
