Hi I have the exact same model / year as you and its a wonderful machine. If you hit any odd things or have q's I have had mine for 5 years and am at 175k miles so a little ahead of you - just drop me a PM.

One word of warning there are organised gang(s) in the UK especially London stealing W124s all models for break up and shipment of parts to the developing world where the W124 is incredibly popular due to its robustness.

I have heard numerous sad stories of people waking up in the morning to find their W124 has vanished- these have also been reported from time to time in motoring press. The E300D wagon is about the most desireable and valuable W124 in the UK so take care. I have friends in south London (expensive neigbourhood) who heard the chink of chains from their bed room during the night - thought it sounded suspicious and turned over safe in the knowledge that they had the oldest and least valuable car in the street. Guess what they found in the morning - theirs was the only one nicked, new SLs CLKs E's all sitting there untouched. The gangs use low loaders and cranes so usually attack cars parked in the the street or on drives close to the street (as was my friends case). You may want to consider fitting a tracker device (£500).

Sorry to sound alarmist but its a real problem especially if you park on or near the road and especially in London.

Hope you have yours for many years though
