After several years gaining lots of insight on Z4's from this site - and having had a 2.2 E85, 3.0 E86 coupe and 3.0 Msport E89 I defected to the dark side in 2015 and bought a 911. But today my 23 year old son bought a lovely E85 2.5 on 41k miles. So I'm back on the forum again, albeit vicariously! I've driven the car and have to say it is transformed with non run flats. Much better ride. And that engine - what a peach, unbelievably smooth. Just need to wait a few years for his insurance to come down and he'll be in a 3.0! Good to be on here again! Hizza
