I'm in the process of using them too... So far so good. The rest is up to me, then back to them for the rest....
I used them a few years ago with an out of state-no title deal on a 55 Olds. Great people to deal with and got me taken care of in about 10 business days, much better then going round and round with the DMV for weeks.
I used them about 3 yrs ago on my 34 ford and am currently using them on my 54 chevy. Mr lawrence is retired from the dmv so he knows and understands the system. He and his wife work out of their home office and are very friendly people. His fee is only $100 and that sure beats standing in line at the dmv only to be told "you are going to need another form completed"
