Some 602s in 124s had timing chain problems. Unless you have records, it's cheap insurance to roll in a new chain and cam sprocket.

In the US the 124 E300 was only available in 95. No 124 Diesel offered in the US in 94.

IIRC the 190D 2.5 turbo was only available in the US in 87 and only with AT. Other 190Ds were available with MT.
