just had clutch, water pump, AOS and other updates to my 996 C4S, which has close to 172,000 miles since purchase some 15 years ago...Callas Rennsport has always been my go to destination for anything beyond my at home garage abilities...my car runs as well today as it ever has, which is as good a testament to their shop as one can profess to...if you live anywhere near the South Bay this shop should be your go to destination as well (they do BMW as well)...
