I'd say drive whatever you like.. in the combitnation of personal taste and affordability..
Thanks to my Avalanche's hourmeter, I estimate, I spend on avg, 73 mins a day in some sort of vehicle. Doesn't sound like much, but then again, my trip back and forth to work is only 10-15 mins a day each way.. So for me, thats a significant number... On avg, I spent more time then in cars than I do talking to my wife.. lol

its a 2004 , we had it for 2 years 1 month.. 910 hours.. 25000 miles (only 27 mph avg heh)
My wife drives it to work, but our drives to work are about equivalent.. and the rest of the time we ride together in it.. outside of that, I probably drive the Camaro alone, about the same she drives the truck alone.. ( go cruising, she goes shopping )

So I thin its safe to say 910 hours reflects how much time I we both spend in a vehicle overall each.
So yea, having a Camaro and Av as daily drivers does suck up gas (off sets savings by our short work commutes).. But we both like our vehicles.. and with the relative amount of time we spend in them, its worth it IMO.
