Seasonal driving is the pattern here. A convertible gets used from May through September, then parks for eight months, and the failures that follow have nothing to do with the odometer. Batteries die on short trips, fuel goes stale, and soft-top drains pack with pine needles until water finds the carpet and the smell arrives a month later.
The heavier cars punish the sitting harder. An E-Class or a GL that spends the winter parked comes back with flat-spotted tires, a low battery and a suspension that needs a mile of driving before it stops complaining. A car that sat all winter needs more attention than one that drove all winter.
Prevention is boring. Drive the car for twenty minutes every couple of weeks through the off-season, keep the battery on a maintainer instead of a charger somebody forgets about, and clear the soft-top and sunroof drains before the first fall storm. Cars that get that treatment come back in March needing an oil change rather than a tow.
