a 97 740i and a first gen Q have a similar design philosophy.
Meaning using technolgy to make a large luxirious car handle as well as reasonably achievable.
The engines are similar in size (4.4 vs 4.5) and configuration (both 32 valve V8's).Even the suspensions are very similiar.The Bmw is a bit heavier and a bit slower compared to a well maintaned first gen Q.
I used to like them a lot until i found out that even newer 740 suffer from trmendous maintenace haedaches that dwarf those of a first gen Q, primarily cuz the Q issues are easily diagniosed compared to the BMW.
Maintenace expesnes on a 97 740 should exceed those on a early Q by a marging within a year or two.
