92 400E Timing Chain

Just got a 92 400e w/ 129K miles. A tech is telling me that I need the timing chain replaced (he has not looked at the car). I called 3 other shops who told me that it is not recommeded. This site has conflicting information on it regarding the same. Does anyone know if it is recommeded to replace the timing chain on this car at 129K Mi if the car runs fine?

Thanks!
