A slight correction regarding emissions testing in Texas. They DO HAVE emissions testing in; Dallas, Tarrant, Collin and Bexar counties. For registration stickers in those counties there is an identifying mark. As long as you don't have the mark, you get an inspection once per year(the initial inspection of a NEW car is good for two years) with no sniff test. The counties above do a dynamometer based sniff test.
Have a great day,
