Stupid question: Is the E28 worth modding or would you devalue it. Such as dropping the 335i straight six in. Makes more power the last few m5 out of the box.
I don't really have enough info or experience with "retro" BMWs to know, but I think unless it's an M5, the amount of enjoyment you're going to get from a decent engine in an E28 will outweigh the potential loss in value. I don't think they're worth that much at the moment.
