Being a working shlub I didn't have large amounts of money to throw around like so many on here. I've bought one new car since 1979 and it was not a good one. But I've only bought 4 other cars since then and they were all used. And all less trouble combined, than that one new 1984 Chevy Cavalier. I've spent probably around $24,000 purchasing those 4 cars and very little more in upkeep. I'm still driving the latest one.
The money I didn't spend on those cars to get that "new car smell" paid for several trips to Europe, South America, and Africa.
However we did buy a new pop-up, it was the first year for the high sides and a slide, so there was little choice in new or used. The 5th wheel we bought to replace it was used, as was the truck to pull it with. The toyhauler we have now was bought new, but there were absolutely no other toyhaulers around that were anywhere near in design. If we get rid of the toyhauler, we'll buy used. And probably still pull it with that 17 year old truck. Buying new is generally a suckers' game.
