Leaks are known to develop in the cooling system. It is common to see more than one part recommended for repair/replacement due to overlapping labor and the use of many plastic parts in the system.

1998 BMW 740iL Problems
Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.
A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.
The rear lower ball joints may wear causing alignment and tire wear issues as a result of the excessive play in these joints. Our technicians tell us a 4wheel alignment should be performed after ball joint replacement.
The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps.

1998 BMW 740iL Reviews
I love this car. Bought it from an owner more than a year ago by just test drive on freeway and I did not check anything. Fortunately, everything works. Just had to replace cats 3 months ago. Found after market and all cost just over $ 400. Very smooth, very fast acceleration. Just close the windows, turn on aircon and drive it on the freeway,I feel like I am a president.

I bought my car in late december of 2010. The previous owner drove 62,000 miles over the life of the car. The car was well maintained and driven by his wife. The car looks like it was never driven inside and out. I had the car looked at and did the car fax to check out the service records. I paid 12,500 for the car I have since spent 15,000 on new valves and head gaskets along with a long list of other issues that are more maintence issues and repairs that you would exspect with a 12 year old car. The good news is that the car does drive great and it is solid at this point. The previous owner never drove out of the city in florida and never went over 40 mph. I will pursue the dealership to cover the valves but as for now I have a great ride.
