W 198/109 (300SEL 6.3) and its damage

Hello dear MB family, I am a member of the “Swedish League”, but I have discovered an interesting Mercedes offer. It is a “300SEL 6.3” year 1972 (so probably one of the last of the series W108/109). This car is supposed to be dry and deregistered in a garage since 1980 (“dry” is credible after the pictures – so the usual 40-60% humidity for rooms seems to be). The car has 24 Tkm. I know oldies, but not with garagesfu Therefore, the following question: what are the stability damages to be feared in relation to this model and the specific storage? MY guess: – tires, cuffs of the wheel bearings – rubber seals door cracked – brakes (sleeps, if made of rubber) – cylinder head seal cracked – tooth and V-belt cracked Is the following possible: – pistons rusted? – auxiliary aggregates rusty and non-govable? – acid damage due to battery or brake fluid? – automatic transmission clamped (converter)? orrectures and additions or comments of any kind very grateful. Friendly greetings P.S.: I am omitted: the car has air suspension. I ask for comments regarding also their age resistance
