IMO everything bad about the S1 doesn't really apply for the Fairmont Ghia (except brakes, but they are fine for your mrs!!)
Considering one is "V8 +
IRS + top of the range" vs "I6 on gas + live axle + taxi model" i think it's a no brainer. There's only 30,000km between them.
But yes they are both overpriced.
And yes I'm slightly biased but I had the same choice 12 months ago and it's obvious which one i decided on.
