Pillarless coupe and the four-seat convertible advantage

Commenters prize the C209's pillarless body and, in cabrio form, its usable rear seats, repeatedly noting it as the only 400-plus-hp AMG convertible with four seats (same-era SLs being two-seaters) and that child seats fit in back. Note the cabrio's rear seats do not fold due to the rollover 'tombstones.'
