I don't see the point in buying an SVT model, spending the extra $$$ over a reg v6 for a more powerful car, only to try and save money by putting reg gas in it. At the very least, you will have reduced performance and fuel economy because the high compression SVT engine is engineered for higher octane fuel. You may as well buy a, cheaper non SVT tour that will be happy with 87 octane, but will give you less performance.
