BMW M3 Competition Sport Touring
The car that BMW never put into production
More than 800 hours of work and lots of money invested; This is the most comprehensive conversion project we've undertaken so far.
Our goal for the project: To build the car we think BMW M should have put into production.

We had long had a dream about an M3 and there was a strong desire to make something special. When we saw photos of the tucked-away prototype BMW M3 Touring, we got excited!
The concept car has been hidden away in a secret garage at BMW M GmbH in Garching, Germany and was shown to the public for the first time in March 2011.
Here's a video of the prototype M3 Touring Concept:
And here's another article: BMW BLOG - The One-Off BMW E46 M3 Touring
The original car
The basis for our conversion project was a 2000-model BMW 320iA Touring that we bought in 2011. The car was well maintained, had fairly low mileage, and it had most of the extras that were available on this particular model. All in all a good basis for the project.
The donor car
We decided to look for a fully functional donor M3 Coupe in England. After some search we found a nice 2005-model M3 CS in Leicester, which only had about 64000 miles on the counter. Of course some would say that it's a shame to take a perfectly fine M3 CS and use it for parts, but this particular car had previously had a category D accident and had been professionally rebuilt. As a former cat. D the car would never become a collector's item anyway, so we decided to use this somewhat seldom car to build a unique car.
The car drove well and had no major issues mechanically or bodywise. It was original and had lots of receipts and documentation to show the history.
Our project partners
Due to the cost of manhours and the general price level in Norway, we decided to look for project partners in the UK and do much of the actual conversion there.
After some searching we found the company Southways Automotive Ltd in Fareham, that had done a similar conversion previously. For the bodywork we chose Kustom Kolors Ltd in Christchurch, Dorset.
