Certified KFZ-Meisterwerkstatt and performance tuning shop in Weiden
Unlimited Auto is a certified independent master automotive workshop (freie KFZ-Meisterwerkstatt) and performance tuning shop in Weiden in der Oberpfalz, Bavaria. The business was founded and is run by Kfz-Technikermeister Christian Klein. A Kfz-Technikermeister is a state-certified master technician — the highest hands-on qualification in the German trade. It means every repair meets manufacturer specification, whatever you drive. Unlimited Auto is registered and certified as a Meisterwerkstatt through the Handwerkskammer Regensburg. That certification is why you get dealership-quality service and repairs for vehicles of all brands, plus high-end tuning — without the overhead.
Before founding Unlimited Auto, Christian Klein managed A.T.U. workshops in Munich and Regensburg. That is real workshop leadership at scale — running teams, meeting standards, handling every kind of repair that comes through the door. He has also competed in racing series, including at the Nürburgring. That experience shapes how we build: we understand what components endure under load, because we have driven cars hard ourselves. That combination — dealership-grade workshop management plus hands-on race experience — is why we can go from a routine service to a Tuning & Performance Build without changing hats. The pedigree is not a story we tell. It is what walks into the workshop every morning.
Master technician and founder of Unlimited Auto. Former A.T.U. workshop manager in Munich and Regensburg, racing competitor at the Nürburgring, and lead on the 1000 PS BMW E36 BiTurbo V12 build.
Unlimited Auto is registered and certified as a Meisterwerkstatt through the Handwerkskammer Regensburg. This is documented certification, not a self-awarded label — the workshop and its master qualification are on record. Why it matters to you: certification ties our work to recognised standards, so you get accountable, master-supervised repairs on vehicles of all brands. Servicing follows manufacturer specifications; complex repairs and diagnostics are handled with current workshop equipment. We are an independent freie KFZ-Meisterwerkstatt in Weiden in der Oberpfalz — brand-agnostic for repair, maintenance and conversions. That means dealership-quality work without being tied to a single marque, and honest advice with no runaround.
We build and repair cars because we love them — Benzin im Blut, petrol in our blood, and it shows in every job. That is not a slogan bolted on afterwards; it is why the workshop exists. Our clearest proof is the 1000 PS BMW E36 BiTurbo V12 build: a 1990s E36 fitted with a custom widebody kit (Breitbaukit) and a BiTurbo V12 engine producing 1000 PS. It is our flagship showcase project — the name Unlimited Auto is the programme. We only fit what we would drive ourselves. From a seasonal tire change to a full race setup, that principle holds: we make what’s possible — and more.
Our reach extends well beyond Weiden through the tuning and enthusiast scene. Per event organiser listings, Unlimited Auto has featured at Tuning World Bodensee in Friedrichshafen, alongside podcast and press coverage. That visibility comes from the work, not the other way round. Builds like the 1000 PS BMW E36 BiTurbo V12 draw attention because they show what a certified master workshop can do when repair skill meets race experience. Wherever you find us — an event, a podcast, or here in Weiden in der Oberpfalz — the standard is the same: dealership quality on vehicles of all brands, plus Tuning & Performance Builds you can trust. This is your workshop.
