50,000 miles in a 35iS

Post by Busterboo » Sat Sep 12, 2020 4:23 pm

2010 Melbourne Red & Ivory White 35iS. Bought December 2016 at 20k miles. Now, 45 months later, 70k miles.

Kept in car port under house. Used almost every day, but no commuting & few runs over 100 miles, although plenty of 50-mile bumbles. Thrashed regularly when hot. Wind deflector works well. Roof up, car stable & quick to maximum speed. Agile enough & predictable in corners, but not a tear-arse sports car.

Problems so far are on page 10 of 'E89 Comprehensive Problem List': front adaptive shock absorbers (replaced under extended warranty), failed wheel locking nut adaptor and snapped n.s.r. 'barrel' spring. Car is still under BMW warranty at about £550 a year.

On beautiful 5-spoke 18" BMW 295s. Threw Bridgestone runflats away - 2 new - after first month. They were so bad, I thought I'd made a mistake buying the car. Been on Pirelli P Zeros since. Two punctures, both within sight of repairer. Each time, replaced both tyres on same axles, so don't have clear picture of longevity. Certainly well over 20k, though.

Uses Sainsbury's 95 RON for 26.4 mpg. Never recorded trip mpg.

Likes: fast, flexible & smooth engine, DCT (very much - car would be poorer without it), various exhaust notes, using it to go on holiday with wife & fitted/~ing luggage, extended leather interior, colour combination (which maximises the overall design), number of compliments it receives (more than any car I've had - and I've had some good ones), occasionally finding new gimmicks (like ski hatch last week) & anything else I don't say I don't like.

Dislikes: Occasional hesitation in 'Normal' at lights & roundabouts, lack of heated steering wheel, reflections from bonnet driving into setting sun (even with sunglasses), ubiquitous E89 heavy boot lid.

Would I buy another 35iS? Yep.

p.s. MoT & service today at 70,336 miles. Pass with no advisories. Tech said, "It's a lovely car."

What tyre pressure have you run during the last 50,000 miles?
Also lol @ 95 Ron fuel. Note to self never buy your car.

Edit: This post is a joke based on busters previous content for the members getting confused.

Your description matches my feeling for the car. It’s horses for courses but I love mine better than any other car I’ve had and that includes a Cayman. My annual mileage is small but I enjoy every moment I am behind the wheel and always look back with pleasure as I walk away when I have parked it. :thumbsup:

Hi, I've been tempted with a Cayman S but also a Boxster S, so interested in knowing what makes you prefer the zed? Thanks :thumbsup:

Performance and handling wise the Cayman is superior. But for me the 3.5is Is the best compromise. It’s comfortable and especially good as a grand tourer. The folding hardtop is a bonus too providing additional security. Porsche maintenance and running costs can be high too. For my needs the Z4 is a perfect match as a second car. I have no plan

Accidentally sent the post before I had finished writing. You can probably guess what I was going to say. I have no plans to change anytime soon. :D

Several factors influenced my choice. 1 I forgot to mention that I carry guns, so, because I wanted a convertible, it had to have a folding metal roof. 2 Porsche service where I live is by an AD and an indy. One is expensive and the other isn't very good. 3 My 911 blew up, so I'm not predisposed to like the brand. 4 Porsches, especially Boxsters & Caymans, are common where I live. In the UK as a whole, the 35iS is uncommon. These things said, both Boxster S and Cayman S are very good, of course, and better in some ways than the 35iS.

So I'm a filthy yank, but what does that translate to in AKI / (R+M)/2? I understand its usually 4-6 points different but would that be more like our 91 premium or 89 mid-range fuel?

UK 95 RON = US 90-91 AKI / (R+M)/2.

Hmm, then whats wrong with using that in a z4? Thats the highest quality gas you can get here in California, at least.

There's nothing wrong with using it. It's what BMW recommends.

The comment from Sunnydays was a derogatory comment on the basis that in the UK you can get 98 and 99 octane fuel in addition to the common 95 octane.

You pay a considerable price premium per litre for the 99 stuff.

Some cars like the Z4M don’t run at all well on 95..

It’s generally thought that using 99 octane improves power and helps clean the intake system..

Hence the exchange between the two..

If you’re not plugged into British humour and some of the exchanges between some of the long commenting members it may go over your head..
