for car yard i have had good experiance with Motor man imports they actually sourced a car i wanted exact to my spec for me took around 3 months tho .. complied RWC warranty etc was all supplied
Autoforce imports was a good one as well sadly they dont bring cars in anymore , more into monkey warehouse stuff
Import one Mark has some nice cars some are a bit overly expensive...for what they are
best bet would be try Prestige imports or Unique Imports or Jspec there arent many decent importers left
