Any suggestions on getting a soft boot for my Z3. I want to find one that will fold up and go behind the seats. Thanks for any info.

If your talking about the this that makes the top look cleaner when you but it down, and goes over the top, Mine cam with mine. call the local Dealer

You can get a factory boot from the dealer (expensive) or on Ebay used for 100 - 150 dollars. This boot will only fit in the trunk, not behind the seats. Z3 Solutions (z3solutions.com) sells a soft boot that they claim will fit behind your roll hoops or in the trunk for 170 dollars plus shipping.
