Happy to help with that mission Dr...we have more than our share of these here on the left coast. Mine is up for grabs too - itchin' to do the sdc...Very nice car...one of these days(probably in 2 years) I'll attempt at importing a 300hp 560SEC or an AMG variant. Such hot looking cars!
I will tell you if it makes sense financially get one. I own one with the 822 motor and it is like nothing you have driven. Now that I have driven 500's and 560 US SEC I don't know if I could go back after driving this. As you already probably know a well kept w126 is a solid as they come but slap that motor in there it is not only solid but is a true performance machine. There are not many cars that will beat this thing leaving a light and merging onto the freeway (new or old).I have been looking for a 560 SEC and live in MN which does not seem too bad in terms of bringing one in. I even went to houston hoping to drive one home this weekend. How much harder is it to find parts for a Euro and is it all parts or certain types that are more difficult.
I will start re(search)ing but appreciate any info.
