My 3.7 Roadster had sports exhaust from Williams, sounded great, fine with roof down, could become a little wearing on long runs with roof up. Make sure car comes with the MBE ECU, if not it will have a rev hang above 3.5k revs which is pretty unpleasant and spoils the drive IMHO. There are several threads on this on TM. If your going to use it in colder weather heated seats are worth considering, really make a comfort difference.
