It's more fun because I like cars - all kinds. I'm not saying I go to dealerships to haggle and test drive for 2+ years, I just like to research, look, learn, etc. To me it's not a chore. If cars were a chore then I'd buy a Honda and call it good for 10 years.
To the OP - non-warranty cars are a gamble, although generally the odds are always in your favor. Long term reliability just sways those odds a little bit, but they still will be in your favor (unless you buy something made in the UK). Weigh that and go with your gut.
