Hi, I am looking to buy another used Honda Civic. Are they're advantages to buying a "pre OBD" vs OBD1 vs OBD2A vs OBD2B civic? Is there an OBD setup that i should avoid? Are the OBD1 OR OBD2A OR OBD2B civics more difficult to get past inspection? more difficult to fix? do any of them cause problems? Am i overanalyzing this? being overly concerned? I am NOT interested in building a race car. Civics that are 91 and prior appeal to me as they are pre OBD and sound simplier. Another 91 civic sounds good as the one i owned was easy to fix -- pre OBD. But i want to make an informed decision. And want to take advantage of the best buying option that i find. In my home state of Pennsylvania my 91 civic had lots of wiggle room when trying to get by emissions. Meanwhile i know that my mechanic had loads of trouble with newer OBD2 models (an engine light that went off 3 moths ago would create problems when trying to pass inspection). Thanks very much for reading and for providing lots of great money saving advice -- both today and in the past. Excellent forum. I want to say that i'm making you guys work really hard for your money but then i'm getting all of this for free, aren't i.
