I spent a few hours yesterday detailing the interior of my MINI. I had just bought a small wet/dry vac for vacuuming the car and other things–it performed great.
When I cleared out my boot I noticed a small puddle on top of the boot mat. It had just been a rainy weekend. But I know very well of the common issue with the boot seal. I thought I was immune with the 2004, but I guess not. I lifted things up to check the battery, and there was about 1-2mm of water in the battery bay. Of course no big deal and harmless at that level, but nothing should be getting in there to begin with. I will now have to check every once in a while.
Good thing I just bought that wet vac…it sucked that water right out!
