I'm also curious where you find a louder exhaust for the 35i for "a small number of pounds".
On AT today the bottom 5 ish cars are 35i at £14k ish average ..the top 5 car ish cars are 35is at £23k ish..

As someone pointed out a bit of work on a reasonator box or baffle box with a 4.5 inch grinder and a welder would get you to the same point.

Given that there were precious few changes to 35i / 35is over its run, paying big money for a newer one doesn’t buy you a lot..

Condition is much more important than age or mileage
The cheaper 35i's are all older and pre-LCI - not really comparing like for like. The 2 LCI 35i's are just as expensive as the 35is. The £14k 35i's are £14k because they are 12 years old and higher mileage. Also they're not orange....

Who buys a £20k car and tales a grinder and welder to the exhaust? :rofl:

Can't you enjoy your own car without snide remarks about people who bought a more expensive one? You bought a great car, so did I. We both win.

May I make an request,... What is Pre-LCI, please?

Concerning the orange 35is on Autotrader which is now at £25,000,... it was only but a few weeks ago that it was priced at £27,500.

I thank you for your response. However, would it be possible, please, to provide greater detail as to the operation of the Hill Start device,... for example, does it actuate at the very instant it detects the motor car is about to roll backwards?

Thank you and kind regards,

MAD
When on an incline the hill hold maintains the brake pressure through the ABS pump for a few seconds when the brake pedal is released.

LCI refers to the face lift cars, starting from around 2013-2014 (I think) pre-LCI is the cars produced up to then

Only difference as far as I am aware with LCI was side indicators and headlights

Netting in the boot came in the 2012 MY along with uni directional paddle shifts :thumbsup:

LCI as Chippie said had revised LED DRLs, side repeaters and some changes to colours and trims. Not much of a LCI :tumbleweed:

Does 'Unidirectional Paddle shifts' indicate that the gear selection paddles move in unison with the steering wheel? If so, that would appear to be an excellent benefit.

Another question, is the adjustable steering column an standard fitment?

I've no idea about E89s but if so it would surely be "a standard fitment"!

Height and reach adjustment for the steering column were both standard on all my E86s, E46s, E87, E91 and current E90.

I'd be surprised if even BMW were so parsimonious they decided to make it an option on the E89.

For a brand new car in its day yes there were a few changes. today compared to a 35i the only thing that isn’t easily fixed to make the two technically identical is a 35is speedo…even that there are people who will do that face plate.

So that’s quite a price premium for a speedo and a few holes in an exhaust?

Just can’t change the VIN number otherwise you could easily turn a 35i onto a 35is for a small number of pounds..

Not that it matters anyway….most people reckon tired adaptive suspension is a bit anticlimactic.
Sour grapes, mate?
No not all..I could have afforded whatever I wanted..my choice was driven by colour and spec not price.

I’m pointing out that if you plan to modify a stock car a 35i can be a better starting point than a 35is.

I tried a 35is with adaptive suspension and certainly wouldn’t pay a price premium for it.

On the other hand if a 35is in the right colour had come up I wouldn’t have rejected for any ideological reasons..

The point being that a decent re-map and new suspension would have eliminated the ‘extra features’ that you are paying for.

But each to their own beliefs..

A 35is is a marketing man’s dream…a bit of zero cost fluff and sell it for a major mark up.

If they really wanted to do a M class car then they could have at least put a decent inter cooler on it, that would have removed the need for the silly overboost and some decent suspension plus a LSD.
Yep, buyer’s remorse.

Unidirectional paddles refers to the fact that left paddle shifts the box down and right paddle (on the steering wheel) shifts up only.

Earlier versions had the ability for each paddle to do both up and down shifts…some people found that counter intuitive and / or confusing

As stated rake is adjustable on all models..no reach option was ever offered..

Dear Comrades,

Once again, I thank you for your more than kind responses to my enquiries; here is another and bear in mind, please, that I have yet to drive a BMW Z4 35i or an 35is, neither have I ever used a Dual Clutch Transmission:

So, the question is, when changing down through the gearbox via the paddle shift mechanism, does the engine, of its own volition, rev-up thus to match the speed of the engine to that of the lower gear to which it is engaging. I ask this question, because a friend had a Datsun with a manual gearbox which performed this very thing,... I though it was absolutely brilliant.

With kind regards,

MAD

That’s not right. Mine certainly adjusts for reach.

Pay a bit less for fundamentally the same car but with a manual transmission, having looked myself I would 100% go for the 35i rather than the 35iS. :driving:

    Yep; rake and reach (on LCI at least).
    All good things come to those who wait. I'm really impatient which explains a lot.
