New to the forum as I have only just bought a classic Mercedes with issues, but I have had Smart Roadsters for over 7 years now. This is my current Roadster, an 04 Brabus in absolute factory standard spec.
Since buying her, I have reajusted the exhaust bracket so she does not vibrate on accelaration any more (that's why I got her cheap!). Fixed the electric roof, waterproofed the scuttle tray, cobbled together the original Becker BE6040 Sat-Nav unit and got it working, new tyres, front brake pads, replaced rear spoiler as was cracked, replaced coupe hinges as were corroded, PIAA windscreen wipers (never underestimate these wipers, they are astounding), foam air filter, topped up the chargecooler as it was dry through lack of maintainence, fixed cracked air-con pipe with new flexible pipe, HEL braided brake hoses and replaced that really hard to get to sidelight that lives behind the water bottle.
She is all good at the moment, and just enjoying pootling around in her. Always good to know other Roadster owners, so drop me a line!
