Good garage for BMW near Hertford?

So the lower shock bolt on the Z4 has sheared whilst we tried to remove it to change my springs.

Now means I have a broken car and I'm 90 miles from home (at a friends!) so no idea where to go round here.

Anyone got any recommendations?!

Thanks for that, I'll give them a call!

No photo but it's buggered!
