I test drove the 1.6L, but as I live in a hilly part of Derbyshire, it was a struggle for it so went for the 2.0L instead
No regrets (so far) - as for speed, as I am now "running it in" I'm trying to be careful BUT as you sit higher from the ground it is VERY easy to be driving faster than you think
I borrowed a 2.0L for a test drive and hit 90+ before I realised I was even speeding!!
Need to keep more of an eye on the speedo - the incredibly quiet engne doesn't help to judge speed either
(AND I am getting better mpg than my old Primera, which was a nice surprise!)
