I have replaced with parts like intercooler, top air pipe etc. From Colt VI CZ2. Identical as those for Smart with Mitsubishi and Smart number on them.
I do high mileage like 35k miles a year and some parts worn badly. Like windscreen hitted with few rocks on Autobahn. Time to replace that 13 years old glass.
I don't mind used parts. Soon most of those parts will be available only as 2nd hand. You can find really low mileage parts. Easy to say that by looking on them. Time always tell truth.
