Default XLR with more than 100k miles?

Hi there,
IŽd be interested how an XLR performs after more than 100k miles.
Are there any specific problems (engine, brakes, electronic, mechanical things) which I have to expect?

Are here some XLR owners with an XLR with more than 60k or 100k or more miles?

Thank you in advance sharing your experience.

The XLR shares the same 4.6L engine as Sam and I'* Bonneville GXP. If they have never been run hot, (ever) alot make it over the 200K mark. But they are prone to head warpage, blown head gaskets, stripped head bolts. Things to consider if you don't know prior history of one. They are also prone to oil and water crossover leaks regardless. At 100k you can expect suspension parts and sensors to begin wearing out as well. The 4.6 is a throwaway engine. When its done, it'* done. So alot depends on how the car was kept up. You could be throwing alot more the the purchase price into one.
