Have Moisture In My Boxster Any Way To Rid It?

[Geof3]

Does the moisture appear when driving or just sitting in the garage? Temp fluxuations can cause condensation on just about any surface, glass, metal etc. If it happens while driving when damp and cold try running your heater with the A/C compressor on, it will help dry the air and is normal. If it is getting condensation while sitting, you may indeed have moisture trapped somewhere. I keep my windows down about 1 or 2” when parked in the garage. It allows air to circulate a bit and keep excess moisture a little better controlled. A garage has wild temp fluxuations and humidity ranges depending on climate. Looks like you are in New Jersey, might be worth considering a dehumidifier in your garage, or secondary heat.
