The car is kept outside under cover. Unfortunately it also sits on the lawn. My worry is the belly and drive train's exposure to ground moisture.

Short of pouring a pad or paving is there another sturdy option to shield the underside?

How about a fresh application of cosmoline?

What year is the car? Is it a galvinised tub?

1984.

Plastic sheeting? Wondering the same thing. Going to have 5 911's here in a few days and can barely squeeze 4 in the garage.

During the winter (here it is wet and usually between 30-45 degrees.) I put the car in a Carcoon. It's a positive pressure bubble that has a heavy basemat that zips up to a lighter top piece. I wouldn't likely use it all year round since it would be awfully time consuming to take the car out for an errand. After several winters it seems to do a great job at eliminating condensation and keeping the battery topped up.

Ground moisture and humidity will kill a car very quickly if not properly ventilated. I would start off with some 6 mil poly for starters ( home vapor barrier ) its cheap and you can roll it out in huge pieces. Will be okay for parking but can't drive over it all the time

Ps even concrete gives off tons of moisture so I use cardboard to absorb it. Works great

The real nightmare scenario is trapping moisture in the car. As long as your cover is vented and air blows under and around the car you will be OK. Don't let the cover go clear down to the ground. Always have room for air movement... If you are setting up a plastic "parking tent" you may want to run a small bathroom fan under it to keep the air moving.

lost a pickup truck mainly due to leaving it on the grass, the bottom gets soaked in dew every morning, and if the car doesn't move it never gets dry before the next morning. Constant wet conditions are perfect for creating a rust farm.

Get it off the grass somehow

^I'm with him, get it off the grass.

i killed an Audi in 5 months this way ...

all 4 springs collapsed in the suspension, exhaust rusted out, alternator pulley seized, starter motor seized, and electric coolant fan seized..

Gees, I had a couple Audis like that too. Funny, I didn't park them on the grass...

My thoughts on the plastic is rainwater puddling beneath the car maintaining high humid conditions as well as a mosquito breeding source.

Thanks for the ideas.

Base mat (poly) is a good idea but you must maintain good ventilation and your top cover must not allow water to pool on it's surface. Also if you use the car regularly, holes will appear in the poly and really should be replaced. I'm not sure if I've heard of a good and cheap solution to your problem.

NEVER,EVER park on the grass.... EVER!

The car is driven maybe once every couple of months to drive moisture from the oil and coat the bearings. The battery is charged as needed.

Sorry Jherriot but it has lived its life with me on the grass. Since around 2002. One car working garage filled with tools and motorcycles. The car always starts right up and drives just fine. No reports from any that have worked on her of water or moisture related issues. Dealing with a fuel leak from a hose at the tank but don't believe that to be caused by the lawn.

I'm thinking of making a raised wooden surface. Put her on a pedestal so to speak.
