i've had 2 targa cars one car had 220+K Miles. Creeked like a mofo. My chassis 74K miles no creeks what so ever. No interior pc's make any noise as well. I can feel a slight flex in the 74k chassis. In the 220 OMG i swear i thought the chassis was gonna split into two lol. I've also owned a 90 hardtop with 155k. Rigid. But i like targa better.
