Dear BMW Colleagues, The Engine on my 1991 325i Convertible just gave out and no hope. I purchased the car in December 1990 and it has approx. 130,000 miles. I checked online for rebuilt engines and etc. It appears that many vendors have engines for subject vehicle, however when checking reviews/BBB many scammers out there. Have any of you replaced an engines, if so what was the outcome - who did you use? I live in the Washington DC Metro area. Your comments and suggestions are welcome and thanks in advance.
