There are two interior fans.

One is for the ventilation and defrost, the other is dedicated to the A/C.

A/C fan is a slam dunk to get to, the ventilation fan is a major job.

If you have to have a defroster to pass inspection, this is a major impediment. If not, once the car is moving, you can get a surprising amount of airflow out of the system with a fan boost.

Rust is the other biggie.

I've been driving my 71 250C to work a couple of days per week recently, and I'm falling in love with this chassis once again. What a nice, classic look as you glance over the hood at that star with the false radiator cap, and the two high fenders. Makes my 83 300D and 90 560SEL look pretty bland by comparison.

These are lovely cars, and have a nice vintage appeal. but remember, they are also old cars, and require above average care and maintenance.
