I'm looking at getting this 1985 318i because i want to get a bmw and it is the right price(~$2000). What are the aftermarket scenes like for 318's compared to 325's? It is 4 door, 5 speed and i started it and it sounds and feels pretty stong. Can i make a 325 that much faster than a 318? Also, it has rear drum brakes. I would definitely want to get a car with discs all around, when were 4 wheel discs an option? I saw a Brembo upgrade/conversion kit for x-drilled rotors, so could i just swap these onto this car? thanks for any advice/wisdom/ comments.
