6 or 4

[Mr Tidy]

I had a 123d for over 6 years before I bought my first Z4C - what was I thinking when I bought that?

I got a cheap Mazda 323f 1.5 litre as a daily for cheap RFL and economy, but after 6 months had to sell it as it was so gutless!

So with my sensible head on I bought an E46 325ti as a daily so I could have straight 6 petrol power all the time. :lol:

OK so the OBC on the 123d showed an average of 48.7 mpg, but my Z4C is showing 33.2 mpg and my 325ti is on 34.9 mpg so petrol is hardly a disaster!

You won't be surprised if I say 6 is the only way to go IMHO. A straight 6 is one of the unique properties of a Z4. 8)

i'd much rather have a 2.0 4 pot turbo than that god awful 23i 6 pot! They are slow as fook! My mates got one a nice low miler, its alright if you wanna sit on the motorway cruising about but for a chuckable sports car its very lethargic. if it was a 35i that was on offer though it would be a no brainer - six pot all the way.

If you want a chuckable sports car why would you buy an E89?? The E89 is a cruiser, don't get me wrong the handling is alright but a Cayman would be a far better choice.

I wouldnt buy one, just saying, a z4 (FOR ME) is meant to be a back road blaster which is a thrilling driving experience - the E89 is just not. (Again, only my opinion before anyone cries!)

No crying lol

The E89 with MSPORT suspension is pants (My opinion) - I felt totally unsettled doing 90 miles an hour down Craner curves - and the amount of understeer is immense. However, for most E89 drivers, I believe the suspension is adequate - as they don't drive the car vigorously.

It was built for the USA market - as a GT and cruiser.

However....

Slap some good coil overs, change your tracking, decent tyres and you have a capable car. Admittedly not as great as a boxer - and you struggle to find the limits of the car on UK roads. I only found limitations of the E89 on track.

But been on a few drives with E85/E86 and not had an issue, with entering or exiting a corner.

I wish you all the best - as I understand this is right on the limits.
