I have question for yall. how easy is it for u guys to repair those cars? i have had now multiple mercedes mechanics tell me that it is more worth to invest in my w204 coupe then into the w203. while i tend say yes, i cant give away my grandfathers car, i am too emotionally attached to it. issue is i have the gearbox module out as it is broken and it has been standing for around three years now with no service and in need of new brakes, besides the sides on the car showing rust flowers. currently i am broke fuck and need a daily, so hence i have the w204, but is it realistic trying to restore my w203 or do i have to give in and leave it as a ornament on my driveway?
