Absolutely nothing, but I did practically rebuild the thing from scratch so this category is irrelevant.
The XR2 mkII is a laugh, I have tried the mkI and found it to be quicker but not very comfortable. The markI is nice but it's a bit boring to drive. So in contrast I would say for comfort, reliability and pure balls out fun the mkII does it for me every time.
How extensive was the rebuild? How much did it cost? I am trying to rebuild an '84 XR2 engine and am having difficulty locating parts. E-mail me if you can help.
