" RennsportKC’s customer service is like no other. Wes even made a "house call" by coming to our home after work to diagnose the problem when our Cayenne could not be driven to the shop. After he told me not to drive the car anymore he offered to take me to Price Chopper as my husband was out of town on business and I could not drive the car. Now that's service! " - Jennifer Diehl Templin,
" Karl has been taking care of both my Porsches for seven years now, from routine maintenance to major repair and modifications. But it is his attentiveness to perimeter details that creates a better whole. He is always doing more than basically requested. When I ask him about some possible ripple effect of the work, he always answers---“I already checked or fixed that”. You always want your mechanic to be like this, but he actually does it, treating my Porsches as if they were his own. This is customer value as its best! " - Murray S.,
" I use RennsportKC exclusively for maintaining and upgrading my Porsches and have been blown away by the quality of the work, the speed and attentiveness that Karl shows in completing each project I ask him to take on and the competitive rates they charge. I give RennsportKC my highest recommendations without reservation and I am convinced that once you’ve had Karl work on your car you won’t go anywhere else. " - Scott H.,
" I’ve owned Porsches for many years and have had Karl and Wes involved with servicing my cars since I met them. The guys built two race cars for me and have worked exclusively on multiple street Porsches, BMWs and even domestic cars since they joined forces at Rennsport. ALWAYS satisfied, ALWAYS treated fairly, ALWAYS priced reasonably. Whether it is answering questions, ordering parts or maintaining street/track cars I have never questioned their recommendation and am always pleased with the result. They are enthusiastic about their work and have an amazing range of knowledge. Whether at the shop or trackside their passion for quality work/support at a fair price is evident. From routine factory-recommended service to prepping track cars I can’t imagine a reason to deal with anyone else. " - Chris McIntyre,
" The guys at Rennsport KC are great guys and very talented. They have worked on 4 of my cars and have done an excellent job. They have accompanied me to race events to assist me with my race cars as well. I highly recommend Rennsport KC they're good people to work with. " - Michael Lyle,
" After getting sub-par service (and paying premium pricing) from several of the local Porsche so-called “experts”, I fortunately found Karl and Wes at RennsportKC. Their encyclopedic knowledge of all things automotive is amazing, they obviously love what they are doing, and are more than fair in their pricing. There are very few people in the world (and fewer service providers) who have earned my complete trust. Karl and Wes are two of them. " - Tim Abraham,
