I dont mean to sound snotty but if anyone can't afford premium gas then they probably shouldn't buy a 42 thousand dollar vehicle.
Wrong - People buy expensive cars for convenience, reliability, and of course prestige. Don't forget that "money saved is money earned". It is very much OK to have the desire to save, be it on gas or any thing else....
However, in today's world, being 'able to afford' premium fuel is a relative concept; what with the way gas prices are going these days. It is predicted to top $4.00/gal for REGULAR in my area before the spring/summer driving season is over... OUCH!! :(
