V Engineering are the go to people. Many 675 owners now moving away from the main dealers and going to V with the knowledge that they do a better job than anyone else.

Agree that anything still in warranty needs to go to Mac, but once out of the warranty period, what's the point unless you like having your pants pulled down?

Brand new 600LT with issues pointed out on collection which main dealer promised to fix.

They lied to me for ten days and then said before they would do anything it had to have an independent inspection which could take 8 weeks. They then refused to talk me and blocked all forms of contact.

I had to sue them in the end. When I won they collected the car but the transport driver lost the V5 and they refused to refund monies until another was issued.

If it hadn't happened to me I would not have believed a firm could be so bad.
Just curious, was this more dealer specific or Mclaren specific?

Dealer obviously was the start but I went to McLaren themselves and they also ignored me.

new gearbox and both cats needed replacing approx 500 miles ago (without car for nearly 2 months) - approx 28k of work!
Lovely LTS! What was the issue that meant it needed new cats and what caused the gearbox failure? As someone else said, McLaren tend to replace for faults rather than fix so whilst the cost of replacement was £28k, it would be interesting to know what someone like Thorney would have charged for fixing the fault.

Fairly sure I read that the Thorney warranty comes with a £10k limit as they can pretty much fix any issue for £10k.

I think the gearbox leaking issue, one of the more costly issues to resolve, was a new unit from McLaren but now a £10k fix at Thorney.

TBC above is correct, poxy gearbox leak which I thought was resolved at the end of the 12C lifecycle, but no, still relevant on cars up to 2021!!! Indeed can be repaired elsewhere for 10k ish. I was more peeved for not having the car for 2 months in the brilliant weather.

You would think Graziano would be all over that seal issue as it won't be McLaren picking up the tab for that; it a suppliers issue.

McLaren charging handsomely for removal and replacing no doubt.

I've read figures of £25k!

Are the gearboxes the same on all models, but with different gearing?

Ive not heard much about 570s gearbox's going pop, so whats the difference between models, 570 to 600?

Maybe a poor batch from the supplier and if you have documentation there have been a recent wave of failures, i would be looking for support from Mclaren as to why, maybe even a recall. Get as much info as you can from others who have been affected and go to Mclaren mob handed, im sure they could do without more poor press and as said elsewhere, they wont be footing the bill, it will be the supplier.

My understanding was that the gearboxes don't actually go pop (i.e. can't be used again) but leak oil and the "fix" from McLaren was a new gearbox, hence the £25k price.

Thorney, on the other hand, have created their own solution via a gearbox rebuild which costs around £10k which I assume retains some of the 'box parts.

My windscreen was damaged whilst in being serviced.

The replacement then developed a stress fracture within 6 weeks.

The 2nd replacement gained a stress fracture whilst being delivered back to me.

The 3rd replacement seems to be holding up fine so far.

Are the 600LT windscreen thinner as per the 675 windscreens in order to further save weight?
their are specific windscreen protection films now available what can / will save a whole lot of hassle , YT search STEK dynoFLEX , ive been to the product testing and this stuff is unreal... perfect clarity and we shot the covered screens with BB guns and they did not crack or event dimple, the unprotected sections shattered. Expensive stuff but a no brainer on rare screens or screen susceptible to damage. Screen changes are an utter nightmare and to me is right up there with things i want left orginal .

The Thorney gearbox rebuild is normally £10k but mine cost £12k so I’d take the £10k as the price for a typical rebuild. Mine was more fked than usual.

Did you have to pay the additional 2k or did they look after you?

The full invoice was paid by GC Motors (after a battle) who sold me the car so I was not out of pocket. The total bill was £15k including other damaged parts.

On my 600LT I had corrosion on both front wings, and one time water entered the door mechanism causing the window to drop (and refuse to remain up) in a horrendous rain storm. Fixed under warranty with no issue though.

Any idea if there are discounts/offers from Mc dealers for 4th year warranty renewal (600LT)?

I have been quoted £2,985 for 4th yr warranty renewal.

Last year I paid £2,685, apparently that offer was only for cars approaching end of OEM 3yr warranty.

Hi there

Been looking at a few 600 LT's and I have noticed some of them seem to have quite heavy wear to their ceramic disc, dealers I've mentioned it too tend to comment we think the previous owner maybe did one or two track days, but unwilling to change the disc claiming they are fine.

One car in particular had really rough disc, they claimed to be fine, doing some due diligence and discovered this car had done a lot of track days, they had another 600 LT next to it, comfort spec with 8000 more miles and the disc looked brand new.

So my question is do people with LT's find the disc wear pretty fast if used on track, I am little shocked that some of the cars I've viewed so far with sub 10k miles have ceramics that are rough and thus worn.

Is it possible to request a dealer to give a disc status report to show in % how worn the disc are?

I thought the only way to accurately measure ceramic disk wear was to take them off and weigh them?

Believe that might still be the case, but it is easy to spot a worn disc visually, like I say look at the cars advertised, if the disc is shiny and smooth, it is decent. If it looks pitted and is rough it is worn and its a 10-15k bill.

If you buy 2 years extension then you can normally get it for around £4.6k instead of the £5+k.
