Pulled out my 220S after 2 decades ,started right up ,a bit smokey initially as I had added ATF to the bores and wd40 to exhaust and carbs before sealing them prior to storage
220S Seats are mbtex and have become rather stiff ,not the supple feel they had earlier.
I am sure someone will have a solution to soften the material,

now on to my w109, i had liberally coated the leather seats with a high quality leather conditioner and that has stood the test of time.
input alway appreciated
