ZM Roadster (z3) - maintenance queries

[adamwakefield]

Hi all
As per post re ZM wanted just on the look out for a z m roadster.

Im currently in conversations over a certain car, and the owners been very transparent in a couple of bits that need sorting on the car.
Wondered if I might pick your brains on potential costs for works on a couple of items.

- Requires new roof - any idea on costs and reputable companies (south east England).​

- A/C not working - not sure if this is just a regass but knowing classic A/C systems know this can often be allot more (rads / compressors etc.). Any views on worst case for an A/C overhaul on a ZM?

I know with the A/C you might argue not needed (roof down) but important as I do an annual trip to LeMans and it can get very hot! 😊

Thanks in advance chaps 👍🏻

Quick Google search:

Supply new roof - around £1k mark
Supply + fit - around £1.5-2k

With the roof you can choose your colour. Same prices.

Air con - most likely a regas around £100

I'll come back to you with prices for radiator and compressor.

Have you actually road tested one? I had one back in the day and it was a horrible thing.

OEM BMW parts prices:

Radiator £434.93
Air con compressor £1325.50

Aftermarket radiator - probably around £300

eBay best to find used A/C compressor

Since you are having a transparent conversation with the current owner, ask them to do a leak test and air con regas.

Maybe they are willing to pay £100 for the sake of getting a sale or you may want to opt pay £100 to avoid a larger expense.

If that doesn't solve things and fix the air con, then negotiate the discount with the current owner knowing the part prices and come to a fair minded agreement somewhere in the middle.

Thanks allot for the input and prices SZM!
That’s very useful as a guide.

Also, agree it’s worth having a conversation with the seller to see if they’ll re-gas to rule that out 1st.

Appreciate yr help !

Adam, you're welcome. Like to help with with BMW's. I'm a big fan boy and learnt a few things over the recent years.

Buy a nice example and look after them and you will be fine. Nothing is unfixable. Try and avoid rust, as that's expensive.

Keep in mind future parts availablity, especially for M cars.

You will slowly become familiar with NLA (no longer available) and unobtamium. I'm sure you've heard of those terms but maybe not experienced it.

Unfortunately, BMW do not support their classics as well as Merc and Porsche. Although I'm sure this is changing for the better as more BMW classics are kept on the road and it's a profitable business line.

Find someone independent you can trust and it's not expensive to run these M cars.

At the right price point it's depreciation proof motoring and these cars are way more fun than current BMW's with all the nonsense tech and being too user friendly my gran can drive my E92 M3 with traction control on and not get it trouble (I hope those are not my famous last words).

To be fair it was a stop gap car, so not the car of my dreams. I felt everything in the cabin was was far too cramped for me. Every time I relaxed my arms my elbow opened the window, which makes you startled at speed!

I just didn’t get on with it at all!
