I am close to placing an order for either a 335i or a 335is. One factor that has recently come up in another forum is the longevity of the turbos. Does anyone know how long the N54 turbos are likely to last before needing replacement? Any idea how the single N55 turbo is likely to hold up vs. the N54 twin turbos? It's a bit unnerving when club members say that they would not own a 335 that is out of warrantee. Typically I keep my cars well beyond the warrantee period and only drive about 6000 miles a year. I'm now beginning to ask myself whether I should even be buying a turbo-powered car. One alternative might be a CPOed M3 for about the same price (about $50,000). On a separate issue, I am about to buy the car for ED from Joern Esser at Passport BMW in Maryland. He is not the lowest bidder, offering a price that is about $1000 over invoice. The low bidder is only about $200 less and is affiliated with a dealership that does not have a good reputation in the Washington DC area. Based on the good review that someone posted for Joern I just decided to give him the sale. .
