There’s something special about the old 5 Series. In some ways they were the high-point of engineering led design. The years we had an E28 in the BF garage were good years. It served as a baseline for what to expect in steering feel and balance.
BMW itself recently took a look back at the E12 and E28. The E12 being the first 5 Series paved the way for a vehicle strategy that continues to this day. The E28 took that concept and pushed it further with higher quality interior materials and technology such as ABS.
