If anyone is seriously looking for a manual 540i, check this out:
I saw the car today when I went to check out a Honda civic with my cousin (he is looking for one, it was the same seller).
I didn't ask much, but from what I was told, it has complete new cooling system : radiator, hoses, water pump, etc etc. Exhaust sounded nice too, but I like stock exhaust all the time.
Not a fan of the rims and exterior color.
That peanut butter interior... wow!
It looked clean and amazing (remember I didn't thoroughly check everything). I loved that interior.
