The convertible roof has leaked on a 2000 BMW Z3 for years. Here are some considerations when choosing to replace the roof.
1. DIY or have it installed professionally. DIY can save $800-$1300 but the install is complicated and easier done by someone who has done it before. There are DVD’s available that can guide you through the process. Recommend getting the DVD and getting a sense of what the work before committing to DIY.
2. Limitations of after-market convertible tops
a. Material – There are a variety of cheaper materials available but the savings is $100 at most. Makes sense to use the material that most resembles the OEM product especially for future resale.
b. Rear window – Our history has been the rear vinyl window is replaced every 5 years. However, the available after-market tops do not have a zipper installed window likely making window replacement difficult to impossible.
3. Costs
a. Materials – $250 to $400 for after-market tops. OEM is ~$1750 from a BMW dealer.
b. Labor Upholstery shop ~$600-800 BMW Dealer ~7 hours labor at ~$800
