I am new to M.B.s and diesels, but I am looking to buy my first. Just like everyone else I have some questions, so here goes.... I am looking at one that has obviosly been repainted. It is a pretty good job but I am trying to determine the extent of repair. All the glass is "sekruit" except the windshield which is "sigla". Is sigla a replacement ? The headlights have been replaced with euro style glass. Are these less expensive than original round replacements, or is this a euro spec car? If so, what would the difference be, besides the headlight?
