If Perfect Fit isn't an option...
Check out Colgan.
Colgan Custom Car Bra and Truck Bras
We got a T-Bra (crawler) for our Honda Element last year and it seems to be made well and has held up pretty good. Can't say about the fit on the beetle though. I know they custom make every bra, don't have stock - so there is a little wait unless you pay to expedite. From the looks of their site it only allows you to choose TurboS, but that should be the only option. I'd give them a call, when I did about the Element they were really friendly and worked with me when I was trying to get a rush order.
