The Infiniti was a nice car: nice on the inside and outside, had reasonable power, and completely forgettable. It was the raita (yogurt) at an Indian Buffet.
My 2007 Infiniti lease. Since the Great Recession was hitting, car leases were absurdly good deals. While I loved the BMW, I had gotten a brake job at 50K miles and it was $4K, and I was approaching 100K miles: time to sell. The car may drive great, but the maintenance/parts were absurd. And I wanted a little more space -- so for like $299/month I could drive a $50K car for 3 years. The Infiniti was a nice car (basically the same motor as the Z), but while everything was good, nothing was great.
