If Colleyville isn't too far then Don Boland is the guy to see. He did work for me about 10 years ago when I lived in Dallas. My 300SD is still going strong. Tell him the Doctor who moved to CA referred you! Good luck,

Also take a look at the previous post

GREAT DFW area Indy. Promise!

I agree that once you go to him you won't go elsewhere.
