I have a 88 190e I bought 8 years ago it had 97.000 on it, I put 300.000 on it last year, and the engine when warm run the same as it did when I bought it. I must admit I changed the oil every 3000 miles. I replaced the transmission last year, and had a valve job 6 years ago. At times it did nickle and dime me but Ive learn to shop around for a good mechnic, and do the minor repairs myself. The cars still looks good to this day and rides like a brand new car. Ill drive the car till it cost to much to repair. Hope this helps you.
