Feedback on high mileage Z4M roadsters please...

If you are wanting a low use weekend / track toy that comes with less financial risk & commitment yet offers decent handling & performance i would seriously consider a 3.0Si roady or coupe :wink: for half the investment they offer decent bang for buck :driving:

good advice buddy cheers will have a gander
 
Milage IS the killer - or.. not really, it’s the stupid engine construction.
However well maintained, it WILL eat thru the rod bearings. Better change before 150000km’s.
 
Very easy car to live with. Change rod bearings at 100k kms, and the vanos/chain guide at 150k, besian kit. Easy peasy. Punches way above its weight at cars twice the price. A few easy /cheap mods and you'll get hooked on track days.

Beware, modding does cause financial strife. :rofl:
 
I had wanted a Zed 4 for a while and felt that if I didn't get an ///M I would always wonder what the ///M would be like. Nearly 4 years on I have never regretted it. I reckon it's still worth what I paid and it always feels special. Even more so now it is just for weekends. :)

Mine has117k miles on the clock. Will get the bearing shells done this year, just for peace of mind.
 
If you head over to M3cutters forum you can speak to plenty of members with S54's at 150k+ miles on original shells / rod bearings / vanos. They tend to have been fairly meticulous with the servicing mind.

They are great cars. Just do the things it needs at the age. Engine mounts are rubber so will be ready for new, engine bolts makes sense and get the bearings swapped about £1500 in all and really as long as vanos behaves it should be decent £ motoring.

great advice. thank you

this is the bit that worries me a little however ... vanos behaviour and 1500 maintenance is not something i am too keen on esp when a sorted 3.0 will cost me 5k

I had the rod bearings done for under £1k all in from a well known and highly recommended Indy, (CPC) you won't do it again in your ownership and it's cheaper than an engine rebuild if the worst were to happen!
 
While your there you might as well get the rest done as its all in the same place, otherwise it will be more labour to sort down the line and tbh the consumables will need doing at the age of these cars.

The benefit of buying a higher mileage car from an enthusiast is that they may have already been done. Im sure the car feels pretty awful on perished engine mounts...

A 5K SI may have its own problems that may cost similar. The benefit is once its done its done and its nothing to worry about as the wear of say the bearing will be down to how you drive it and you will know which is nice. Its doubtful it will fail in the lifetime you own the car.

If the primary reason is to track the car I would have it done as the car takes a different kind of hammer and may bring out gremlins that would take much longer if it were on the road. :thumbsup:
