Mine has spent the last 6 years in an open, but private parking lot (shared between 4 blocks of flats, mine being one of them).
This included nearly 2 years without moving after it was stolen and trashed and I did 90% of the repair / rehab work in the car park and not once did any of the neighbours complain about my "old abandoned car".
The only problem is that it (and I) suffered the blazing sun in summer and sub-zero temperatures in winter, but the car put up with it better than I did!
Next week I'll be moving into a flat with an underground garage in which the E30 will be blessed with a parking space

but I won't be able to work on it in there though.
The E39 will stay in a similar private car park open to the elements.....
These are sensations as hard to forget as they are to ignore.....
