For anyone still following/interested, I just discovered some interesting developments today.
I got the carfax to the car, and noticed a service entry from acura of stockton. I gave them a call, gave them the VIN, and the very nice man on the other end of the phone told me he knew the car / owner well, and that this car was very well taken care of! He gave me the news, and all the service history on it.
The Good: The car was very well maintained, and at 33.7k miles (around Jan of 2013), it had its timing belt, water pump, all coolant hoses, brake master cylinder etc (due to a small leak) replaced, along with new spark plugs, and a valve adjustment. The oil light was also flickering a bit, so that was repaired/replaced along with a new oil pump unit. Hood struts were also weak, so they were replaced as well.
The Bad: Apparently, the car was broken into and stolen, but immediately recovered. The door locks were damaged in the process, which was fixed and repaired.
Misc: First owner had it in scottsdale, AZ up until 29k miles, and then a second owner bought it in SF up until it was sold to me recently. All emissions/smog tests in its life passed.
All in all, the call gave me a big sense of 'peace of mind', knowing when the belts/hoses/pumps were done, and the service manager I spoke with assured me he knew the owner/car, and it was very well maintained and taken care of. He told me "your money was well spent, the previous owner put a lot of money in this car keeping it new, you practically got a new nsx!"
Sweet
Now, just have to wait to get it back from Don!
