Neither my 190E nor my S420 have ever required a major repair. (Knock on wood.) All of the work I do on them is regularly scheduled maintenance or replacing plastic or rubber parts that have become brittle and broken due to age. I have absolutely no complaints about either of my two vehicles and have never regretted purchasing them. The main reason I come to these forums is because I enjoy learning everything I can about the technical aspects of my vehicles and to assist anyone who may need some advice on their MB. This forum has saved me tons of money by allowing me to do maintenance myself, especially on my S420.
