The '97 and newer W140 cars are much better than the early (92-96)models. Most of the AC problems and electrical gremlins that you hear about were corrected by'97.
I plan on replacing my '92 300SE with a '97 model when the 92 wears out,(it has 273K now), or I get sick of working on it.
Go with your heart , after driving a W140 for a week, you will never be happy driving anything other than an S Class Mercedes Benz.
