This state website has lots of useful info. You'll find telephone numbers of those elusive auto licensing centers, Accident report forms, address changes online, and THIS IS GREAT, no more standing in line...YOU CAN RENEW YOUR TABS ONLINE.
You can buy or sell used cars here. Thousands to choose from. Great search and research features. A personal favorite.
