Wishing you luck!
Good man.
Mine has 199k miles. Wife driven, Seat leather pristine. I mean it has been babied from mile 1. (I dont think she has ever pressed the skinny pedal enogh to downshift) So if i was faced with 5k, 10k to get another 100k miles, it would be worth it (for me). Heck, even give the car to one of the kids when she got tired of driving a dated car....
I tore down a Q45 engine in my unheated garage during xmas break many years ago...so feel your pain. (And that was in the brutal califonia cold!

)
Keep us posted!
