1. Join DFW AutoClub
and ask question #1 there.
2. Inspection is yearly. It's an OBDll read plus a safety inspection. You get 2 years on a new car.
3. There are 4. None are great. Most people are going to Classic up in Plano. Pat Arnold is the M guy. Again, ask on DFW AC
. Lots of BMW guys on there. There are some good independents such as Autoscope which has 3 locations and is a Dinan dealer.
4. Look at the Area Events Forum
on DFW AC. You'll want to attend Cars & Coffee at least once. It's the first Saturday of every month at Classic BMW in Plano. DFW AC meets every Saturday morning up in Frisco. There's a big club scene, if you are into that. Ask on DFW AC
. There is a large and diversified membership from really old guys like me who know nothing about the club scene to much younger guys who know pretty much everything about it.
