Well it makes me wonder whether i should sell the 300 SDL and buy the '84 300 SD. I've seen the service records of the SD for over the last 10 years, totalling $15k. These service records inlcude new brakes, motor mounts, new seats etc. This used auto dealer wants $4k for it and it's in great shape. The 300 SDL needs a new brake job, probably new rotars and suspension system. I need the climate control worked on and the springs in the seats are bad. It does run great though and the body is in great condition. Either way I guess you have to do maintenance on vehicles over 10 years old anyways.
