I'll keep an eye on eBay, thanks.
Yes, I discovered the whole offset thing after I'd already bought the rims
and hunted down tyres! After destroying the front tie rods I discovered I
had to get 7mm spacers specially made. I count myself lucky that this
didn't also require modifying the guards for clearance. You are right
though, after all the tears and trying to find a design of wheel that
looked like Merc had intended them for this car, I'm very happy with the
improved looks and steering feel.
