I had one for 4 years, absolutely loved it. Always made every journey special, get noise when you fire them up from cold and the exhaust note gets richer and deeper as the car warms up. Used to see 30mpg on a motorway run jogging along at 70ish
. Did a couple of runs into europe with it and was great in the Alps and Dolomites.
My mate always used to thorw the Datsun line at me, then we did a track day and he went quiet when he couldn't shake me in his Z4M.
