Mercedes 190e, which year should you choose?

“Of the 2.6's, the 92 and 93 are the ones to get because they got rid of the "skip gear" bizarreness in the automatic gearbox.” - Spectre, source: https://forums.finalgear.com/questions-and-answers/things-to-look-out-for-when-buying-a-mercedes-190e-and-or-a-e36-36185/

“I advise staying away from the 2.3s on general financial principles (save for the 2.3-16 and 2.5-16). Others have advised you on the head gasket and engine mounts. Please note that all of the Merc engines are known to have issues with oil seepage from the outside of the headgaskets and from the front main seal. These are not usually much more than annoyances and are not fatal to the car, nor do they indicate that you should reject the car.” - Spectre
