I just wanted to belatedly thank all those who responded. I recently bought a 300sdl, 1987 which I’m bringing back to life (an overstatement but it sat for an extended period). Pretty low mi with172k etc. But when I’d leave it and get back in the 89 420, the 420 just seems more modern and sophisticated between the Seats, suspension, and the difference in condition in the two. But as I’ve continued to improve the diesel it seems to be ‘gaining’ on the other, wonderful road car, and I may just have to donate the 420 and be done with it. I paid $3k for it, drove it for 3 years and that’s not too bad. I think it needs rings, etc, and I’ve been chasing gremlins most of the time I’ve had it. But on a good day... (makes me want to find a way to keep it). Interior is great, exterior looks good from 20 feet, maybe 10 feet on sides and 25 feet on roof - haha. Thanks again; passing on the transplant.
