No not standard. i have a vr series 2 acllaim and its got it. i think only some of the acclaims and calias came with them..
Option on Executive until VT The IRS was standard on the Acclaim from its introduction with the VR I think. It was also standard on the Calais, but not the Berlina (again I think). It was optional on Executive models for $499. I optioned it on my VS S2 in 1997.
No they don't, you can tell by it's written on your dash, usally below the radio. Mainly BERLINA's and Calais's Have IRS. NO WORRIES Now go sick on the burnouts
