The 240 is, IMHO, the almost perfect car in this respect. For my purposes, it has EXACTLY the instrumentation and controls it needs. It even has what I'd call the "thinking man's idiot light," the flickering headlamp dash light that indicates the need to replace the front brake pads.

I've now got two of the jaspers, one auto and one stick...I aspire to have diesel W123's for the rest of my life...even if that requires not living too much longer!
