Why Unlimited Auto: certified master technicians, modern equipment, petrol in our veins

Unlimited Auto is a certified independent master car workshop in Weiden in der Oberpfalz, founded and run by master automotive technician Christian Klein. The qualification is state-awarded and the business is registered with the Regensburg Chamber of Skilled Crafts. That is a verified credential, on record with the chamber. Before going self-employed, Christian Klein ran A.T.U. workshops in Munich and Regensburg as workshop manager, and he has raced in several series himself, including at the Nürburgring.

We fit only high-quality parts and work with modern equipment so your vehicle stays in top condition. The same standard applies to tuning: we only fit what we would run on our own cars. At Unlimited Auto, the commuter with an oil warning light glowing on the dash gets exactly the same straight answer as the enthusiast planning a widebody build.

„Great service! Twenty minutes before closing, a friendly member of staff spontaneously checked the oil level on my car and ruled out that the oil warning light was a problem for driving on. He also took the time to explain exactly what was going on and what the next steps would be, even though I am not from Weiden and not a customer. Thank you so much. Their heart is in the right place.“

We do what is possible, and then some

Our best-known project is a BMW E36 with a bespoke widebody kit and a V12 bi-turbo engine. On an independent dyno it makes 1,012 hp and 1,182 Nm at 2 bar of boost, after eight years of building in our own workshop. Alongside it sit the BMW 328i E46 widebody "PANDEM", a BMW M6 E63 on air suspension and an ongoing Lamborghini Countach REPLICA with a BMW M73 V12 bi-turbo. Exactly the same craftsmanship that goes into …
