a yellow 997 carrera cabrio is featured in the current german ams.

they say that coupe looks nicer, (i agree, yet still prefer top down driving).

its approx. 85 kilos heavier but with very sturdy body.
lowering center of gravity due to top removal should improve cornering.

accel. 0-100 kms in 4.9 (coupe 4.8)
top up max speed like coupe 293 km/h
top down around 275....suffice to dry your hair after a shower if slightly more expensive than your average hair dryer....
