Well I know that the 35is will leave a big smile but I can assure you that after my 3.0si the 35i will certainly give me a big smile with more power and a great sound and I can't wait to get it :thumbsup: the thing is with a used 35i or 35is there aren't that many around and for me I wanted red leather so finding the right car and colour combination and spec isn't easy so a black with red leather 35i is coming to my house next week :)

Of course if you are in the fortunate position to buy new then a 35is in Valencia Orange would be the one for me but as mine is a weekend fun car I didn't want to spend daft money :) and let's face it either car is a superb car with over 300bhp a smile is guaranteed 8)

Hi Shortfuse, I couldn't find a 35 to try hence my paranoid rambling :D Andya 1's right though i'm sure, either 1 will be awesome. I do question the sanity of blowing so much on a toy but keep telling myself 'life's too short..life's too short' :oops: Thanks for the input chaps. :thumbsup:

I drove a 35i before a 35iS and didn't like the 35i - the power was far flatter over 4K (which I guess is adressed by the extra 30bhp of the 35iS).

More importantly for me the suspension was not 'adjustable' in the sense that the standard suspension in the 35i I felt was rock hard compared to the 'std' setting on the 35iS adjustable suspension which I found acceptable. The 35iS I have is on 326 alloys and the 35i was on 296's. It shouldn't make any difference but the 35i was a hugely harder setup.

I'm pretty sure you can spec the adjustable suspension on the 35i also - but it is standard on the 35is.

The way I see it, the 35is is basicly the same car as the 35i but has most of the optional bits as standard, plus a slight engine tune & the noisier exhaust.

Given the costs of the options that are included it was a no brainer for me - I would have got the engine tune, extras, plus exhaust anyways :)

If you get the chance to try both back to back, the 'is' version gives you a lot more specialness for the money - definitely recommend trying it.

When I test drove the 35i that I am getting it felt and went superbly and for me it will be a massive step up from my E85 3.0si so I will be more than delighted driving the 35i, I agree if you are buying new then why not get the 35is but for me it is a weekend roadster and the performance and ride will be perfect for my needs and buying used the 35i and the 35is are a bit harder to find in the colour combination and spec that I wanted plus I didn't want to spend 20k on a weekend car and I am getting mine for less than that so I will be in wide grin mode when I pick it up on Friday :driving:

We all have different opinions on which model to get and I am no expert driver and I wouldn't be able to tell the difference between the two cars apart from the 35is being more powerful but that would be the extent of my skills in telling them apart :)

When I was getting the E85 3.0si there were people saying you really should get the M but when I got the 3.0 it just blew me away as the performance was so good and it felt brilliant to drive and not having the M didn't bother me at all as that 3.0 felt so fast, so this 35i is probably going to make my wife Linda pass out when I accelerate :D

They are both great cars whichever one you get :thumbsup:

£1055 is the difference between the i DCT & iS. The adaptive suspension is £660, having driven Z4s with & without adaptive suspension on the same wheels I'd say it's a must have option. The remaining £400 then pays for an extra 25-100Nm of torque once over 1275rpm (exact figure depends on rpm & if over-boost conditions are met). It's worth noting the 35iS produces about the same torque at 5900 rpm as the 35i does at peek torque, around 2500rpm.

Great reply but that all means nothing to me and many others on here :D I promise you I wouldn't be able to tell the difference with the suspension and as for the torque at a certain rpm it means nothing to me, if you read the performance figures of the two cars there is very little in it and was the same for my facelift 3.0si compared to an M not that much in it, I know that the 35i will never get near its limits with me driving :) I do like some straight line speed and a great sound but quoting me all these figures means nothing to me and probably many other buyers as well :)

I do understand if buying new and it is costing a small fortune anyway then the extra for the 35is makes sense especially if it is your main car and I would probably do the same but mine is a weekend fun car and it will be perfect for my needs.

Hum... okay in the same gear at the same speed the 35iS will be accelerating 6-25% faster depending on the exact conditions. In 2nd gear the 35i hits peek acceleration at 23mph & from then on its rate of acceleration is dropping. The 35iS at 54mph is accelerating as hard as the 35i at 23mph & it has been accelerating faster than the 35i since 12mph. You'll see the same pattern in all gears but the speeds will be different.

Does that make any more sense or should I just shut up? :rofl:

:rofl: probably just shut up :D as I said it really means nothing to me all I know is when I drove the 35i it went like a rocket and sounded superb and felt and went so much better than my 3.0si and that will do for me :thumbsup:

Both are plenty fast enough to get you into serious trouble! :D

I've been lucky even in my pedestrian 3.0

I think the 70mph speed limit can be broken in third gear???

Some interesting and valid points on this, much appreciated chaps. I can see both sides from Andya1 and Techathy, Andy's right that the 35i is ample imo but also Techathy's point on the adaptive suspension is something i'd rather have than outright performance as I just won't use all the power available in speed hence i'm mulling a 28i over and i can't realistically use the power in the M, you simply run out of road and anywhere near full throttle after 2nd gear is points or a ban or a cuddle with a tree as Ronk and Jimbo are saying, but then I really like as much low down torque as possible and the adaptive suspension would be great to have. Hmmm more thinking time needed. :headbang:
