I am looking for a W124 V8. Should I go for a 92/93 400E, or a 94/95 E420? I think I want to stay away from the 500s because of the price/exclusivity/insurance and so on. The only difference I know of between the 400E and E420 is the front grille/headlights and white turn signals. Are there any major differences in engines, trannies, mechanicals, other cosmetics, or anything else worth noting, or "bad spots" on either? Recommendations? Thanks for any help.
