4.7's are very good value compared to 4.2's now. There are several 4.7 cars up at mid thirties, with one higher mileage car at virtually 30. But it's still hard to get a decent 4.2 at much below 30. Strange, as I would expect a larger gap. Early 4.2 cars need to be cheaper. The later bigger engined car is so much better, why would anyone now buy an 08 4.2 for just a few thousand less than a similar mileage 4.7?
I must say I'm very tempted with this particular one, but I really really really don't need another car (or so I keep telling myself).
