e39 M5 restoration - which company?

[Ian CG]

Good evening good people,

I’m asking as per the title really, anyone know the ‘go to place’ for a full resto of an e39 M5?

I’ve got a 70k mile car, in pretty good condition with no corrosion. Looking to get basically a new car at the end of the process.

I’ve had a trawl around and like what Redish do on the their underside resto’s, is there anyone else I should consider? Quality is paramount, I’m not looking to cut any corners.

Thanks in advance!

Thanks Richard, some names I didn’t consider there. Very helpful.

Thanks again all. I approached Retropower several months ago, could still be an option. Their work is the standard I’m looking for. I would say body shop quality is perhaps the most important, not just paint quality but preparation and protection of the bits you don’t see, I don’t want to be seeing even the tiniest bit of rust even 10 years down the line. I guess the mechanical bits can be farmed out to whoever is the best for that particular component.
Another aspect I’ve been thinking about is getting rid of all of the computers in favour of a power distribution unit. The various modules are going to become an increasingly big PITA as time goes on. Anyone know if this is possible whilst keeping all functions? Concerns with this are ABS and airbags, also engine control, particularly VANOS.
As far as the man maths is concerned, if I can get a new e39 for the price of the latest whiz bang M5 then I’ll be happy. Having owned every M5 from the e39 onwards, I know which one I would rather have for the money, also where that money is safest when looking in terms of depreciation in the longer term.
I think my next step will be to see past work of the companies above.
Again, thanks all, much appreciated.
