We are rapidly approaching that point. I haven't felt any pressure from the price until now. We drive about 25,000 miles a year. It now costs me $45 to fill the tank of my Camry. I cannot imagince what it costs to fill an SUV or a full-size pick-up. I'd LOVE to have either of those, BTW, but the costs of running them are prohibitive.
Hit a day last week where it cost me $105 to fill our two vehicles.
I drove my 77 Benz V-8 powered 450SEL (12-14mpg)yesterday, and filled the almost empty tank. I had forgotten about that tank's capacity, and not paying attention, at $2.279, I handed over a $50, and a $20, and got a Coke, and sandwich with the change!
A friend has a 4WD Ford F350 Dually, and gets about 7-8 mpg. They haul their horses with it, and when she filled the twin tanks last week, at $2.199, it cost her almost a hundred bucks!
I can afford the fill-up, but I have started driving my Volvo wagon more (28mpg), and leaving the Explorer (18mpg) for when I need 4WD.
My wife keeps her 300ZX in the wind, and just keeps it pumping! She wants an older 280SL, and I am looking at whether I can save on gas expense, with it. We drive all of our cars, but not as much, these days!
