I have owned a couple of Eg6s.Both are SiRs where the 1st one was a late `91 model SiR and the current one is a `93 SiR.Both comes with grey interior/trim.Engine is a big Vtec and it includes power steering,AC and power windows as standard accesories.The wiring connector is orange in colour on the `94 model.Grey connector on the older model.
As far as I know,sunroof,LSD,door-panel tweeter,double-din console are optional accesories.
The major differences are the interior.The SiR II comes with black(batik) seats and matching door-cards,black carpet and floor mats.The SiR IIs production year starts from 1994 untill the
end of the Civic EG production year,1995.
Thats all the (necessary) information that i can recall at the moment.Just add-in more info IF i have missed out any,ok?
Thanx!
