Believe it or not... If you put a decent aftermarket suspension like Ohlins, KW, etc this Nissan could be as fun as M5!!!
When my wife changed 2000 Maxima(Koni sport + H&R springs, 160K kms) to 2010 M35X(stock suspension, 10K kms) in early 2012, she said the new M35X was unstable and difficult to drive!!! (Even I ask her today. She still say the same!!! )
