Desisuperman: Neither of us are "large car people" - we've both driven smaller sports-oriented cars in the past and a 5 is already larger than we'd normally go for - if not for the kids, we'd probably be looking at a 3. The secondary issue concerns reliability issues - a number of my friends have 7s and each one loves their car but bitches about the cost and frequency of maintenance. I did initially look into them, though.
europrince: I was looking at a 5 mostly because of space in the back. If yearly upkeep is $2k, I might be able to live with that, considering you're likely to spend close to that on a p.o.s. Yeah, you may have a lower initial purchase cost, but you'll also have a lower resale (or no resale?) over 60-70k km... What do you consider a "lot of driving"?
