Have never had any mechanical issues. Drove it in east coast city traffic and the mountains in colorado- handled roads great and heated seats with convert top down were a luxury. Bought it because of the retractable roof- the SLK was the first convertible to do this and I never had a problem with it. have owned several other Mercedes from sedans to SUVs and this was definitely the most fun to drive, body style looked great ten years latter, paint held up- silver, but the interior was starting to wear- florida heat may have been a factor- the red paint on the dash and console was starting to melt and peel. So, with regrets I just traded it in. Other than routine maintenance no major repairs.
