I am seriously considering getting a 348 from Martin and wanted to make sure I have all the bases covered regarding this model. If I have missed anything, please let me know: Motronic: 2.7 are more reliable than the 2.5 versions, but since the car I am looking at has an upgraded Challenge ECU, then should be no problem? Never heard of the Challenge ECU before. Wider track: the wider the better! This one has the Speciale rear track (subframe?) configuration, so the handling should not be as tricky as others claim. Cats: many say to remove them to avoid potential fire hazards. I know environmentalist will scream, but this car in particularly has punched cats. Clutch: my understanding is that the single plate are more reliable and better overall. This car is a double clutch with metallic plate, so not much to do, but wait for it to become an issue later on. Alternator: the AC Delco ones are as good as boat anchors for cars. This one has the upgraded Nippodenso unit, so that is about as good as it will get. Wheels: many say that putting light wheels, especially 18"s make the car handle a lot better than stock. This car has the Challenge Speedline rims on it. Interior: apparently 348s are known for interiors that do not hold up well with time. This car is no exception and since it has been extensively modified, well, lets just say its not concours edition. Second gear: I have read that 348s have issues when the cars are cold and shifting into second gear can be a challenge. Apparently this has to do somewhat with alignment of the shifter cables and the use of Redline can help a bit. Overall the cars are more reliable than what others make it to be and give it a bad rap, hence the lower price on them. There is an infinite battle as to whether or not is better than a 328 or if the premium to a 355 is worth it. I actually like the way it looks, and for the performance, I believe it cannot be beat, taking into account price. And yes, get a PPI no matter what before buying. Am I correct, or am I missing other things? I have spent some time in the archives and this is what I believe to be a very brief summary of the posts I found. Thanks in advance for the replies/comments/suggestions.
