Well, i've looked at 2 more L322 and 4 more P38's. One of the cheaper P38's had moss on the engine block and several gallons of water in the spare tire place. The most expensive P38's also didn't come without problems. One was a bit strange, when you let go of the gaspedal a whining noise appeared. Sounds like gearbox issues to me. They still had to look at it, getting that fixed might increase selling price he told me. I've called the guy from my previous post again. Leaky air suspension and some sweating are issues i can live with.
i've never looked at the 4.0, but if that 4.6 doesn't drive nice i might just start looking at those as well.
