I recently bought a cheap BMW 635 CSi

Here is a BMW E24 635 CSi that was last on the road in 2001. I purchased this car sight unseen on Ebay. The gamble on my part is that any rust is insubstantial and can be repaired. Will this turn out to be the case? In ths first episode we receive the car have a brief inspectiaon and give it a good clean!
