I had two count them two lemons in my car-driving experience - a pricey Peugeot (the worst car I've ever owned) and an Audi (the second worst car I've ever owned). Both bought new and both broke down regularly and cost me thousands of dollars before I finally dumped them.
Best car - my current Infiniti I30. Prior to that was my second best car - a preowned Infiniti M30 (no longer made - in fact, it was already out of production when I bought the preowned in 1996). The M30 was great and great-looking. When The Faculty sold and we got our rather large payments, I bought the I30. I have never had a spot of trouble (knocking wood loudly) with this car. In fact, I said to the service person that it was the most amazing car ever, and he concurred that that model is the workhorse of the Infiniti line. I've had it for six years now - normally I would never keep a car six years, but I'm so grateful it's been so good that I just want to keep it. Besides, its looks haven't dated at all and it's in very good condition. And for some reason I've put very little mileage on it - only 50,000 in six years. In all that time, I've only had to replace the brake pads once, the battery went last year and I replaced that, and until today that was it. I knew there were going to be brake problems on the rear brakes because the sensor was making a noise - so they have to redo the back brakes (fronts are perfect), they have to change the windshield wipers, and, after six years, new belts. All this under seven hundred bucks - I don't think I've spent more than 1500 dollars on this car in six years, which is pretty amazing if you ask me.
