My previous vehicle was a 2002 Supercharged Tacoma. It was a beautiful truck, very practical and at 52,000 miles could be mistaken for brand new when driven. The only thing I ever replaced was a $4 spring squeaking in the clutch pedal. I got rid of it because ultimatley it was boring.
Now I have my E34. I've already replaced a coolant hose and the heater core needs to be done. Replaced some small stuff like the gas door hinge. In the end I couldn't be happier. I think part of it comes down to me working at a desk in front of a screen all day. I enjoy taking time to tinker and work with my hands. Even if it is frustrating at times (see my recent post) it's fun and enjoyable for me.
