Title Problems

[TurboDomestics]

So I bought a dsm shell awhile back, and didn't pick up the title at the time of purchase. Its been quite some time since then, but now the car is running and ready for the road.

I talked to the owner several times for the last 2 weeks, but he was always out of town working. Now i have been trying to get in touch with him the last few days and he hasn't answered his phone at all.

I don't remember his address and only have his cell phone number to reach him.

Any ideas on what I should do?
