Just passed 139k which is quite the milestone for an S type in a sense.
Wow 270k I don't know whether I'll get mine up there, but for the year and mileage mine is pretty solid, all metalwork is original.Tis but in the prime of it's life Henry, our old 3.0 nearly doubled that at just over 270k before the tin worm got the better of it. Really thought we were going to make the 300k, but in the last 12 months of it's life, the rust really got hold. Not so much the sills, but lower boot corners, floor/chassis rails, sub frame and lots of bit's and pieces. It was just too daunting a task for me now :-(. The way you look after yours, it'll still be going strong for years yet!
I'm assuming your 270k motor is the 1999 one in your sig?
