I’m an absolute noob when it comes to mechanical stuff. It sure don’t sound right inside the showroom, sloppy flappy curry morning-after noises aren’t normal but surely the dealer would know to fix it if we’re misfiring on a cylinder or two.

question though: I don’t think the spec sheet says P30 and I think those callipers are bigger than standard r172 55?

I actually like the colour, but does it have aftermarket brakes? If so, then does it suggest a fair bit of track work?

even that wouldn’t put me off, but I would spend a couple of hundred quid and get a professional merc specialist mechanic to check it over. Turbo recommended one, check his posts.

good.luck, it sure is purty.
I really don't think it's had a hard life. The previous owner, a lady had also adorned it with a glitzy cover for the info system knob. The service history is solid and the mileage supports it. I'm gonna check the exhaust valves tomorrow and take it from there. Might get them to push it out of the showroom and start it again if the valves check out ok, and if they don't, they'll be keeping it a bit longer till it's sorted. As far as the brake calipers are concerned, you're the first person to mention the size. I'm just wondering what else someone is going to point out!

Just had a call from the dealer. Apparently the exhaust had been modified. There were, according to the sales guy, who has been on leave for 4 days, no catalytic converters on it🤷🏻‍♂️. They have sent it to a local performance car 'specialist' to get it sorted and it should be back today. I asked if they thought a previous owner had modified it to make it sound 'better' but they said they didn't, and couldn't know.

Apparently it's having a replacement system where required and a remap. Dealer just told me it'll stand him about 1500 quid.

Got the chance to speak to the guy who owned the car from 3k to 28k miles yesterday. He seemed genuinely upset when I told him the car had been 'modified'. Said the car was totally stock when he sold it and had wanted for nothing during his ownership.
Back to the now, I also visited the guys who are righting the wrongs in terms of the butchered exhaust system. Even though I wasn't paying for the work, they could not have been more accommodating with me and what they were doing. The old system had had both cats removed. The lambda probes were just tie wrapped out of the way! These guys had told the dealer what it should really have, and apparently he said yes, do whatever you think is best.
So now it's having 2 custom stainless downpipes and sports cats, (whatever they are). They took me under the car and showed me the first pipe in place which was being built from shorter lengths of tubing individually welded to form the bends. At the time it was just tig/spot welded, before being removed from the car again to be welded properly. I wish I'd taken photos as I believe the finished product will be top drawer.
So thanks to the guys at Top Gear Performance Top Gear Performance – Exhaust Specialists in Doncaster for convincing the dealer to get the work done and to the selling dealer for sorting it out with them. Hopefully the car will now be. everything I'd hoped it would be.

that’s a great result. But you need to consider the implications of selling the car on with a completely non stock exhaust system. I’d love a car that had a modified exhaust including down pipes and a remap, but you need to consider this as a modification and whether you’ll need to disclose it to your insurers.

Good luck

I respect your opinion but the system is not completely non stock, only the down pipes and cats as far as about the middle of the car. Everything back from that is stock. The remap will be solely to match the new exhaust and cats with the ECU and remove the error codes which were thrown up by the previously butchered exhaust system. It is not being added as a performance boost system, merely an aftermarket replacement, though I'm assured that the performance of this system will not be less than the stock system and is certainly not a system to increase the noise, indeed they've said it might actually be quieter. Looking at the work carried out by this company on their Instagram page, I am under no illusion that they are highly skilled and know their stuff. I accept that there will always be an argument with some people that a car like this should only be fitted with completely stock parts. When it comes to replacing a section of the exhaust with a quality handmade alternative, I don't hold with that view.
The dealer rang me today to say that he had brought the car back and his mechanics had asked to put it on the ramp to look at what had been done. He said one of them described it as a work of art. 🤷🏻‍♂️ I'm buying the car and hope I don't need the luck you offer, but thanks for it anyway

It will be interesting to hear how the car sounds with aftermarket sports cats fitted. Would appreciate a new video with sound when you get the chance. Did the car not have the check engine light on with the cats missing and lambda sensors obviously not in the exhaust?

Thinking back to the brake calipers I thought they looked stock apart from the colour, so guess it was just a refurb of the originals.

Enjoy your new car!

This is the thing, there were no warning lights on the car when I drove it, so I don't know if they had somehow been mapped out of the car by other botherers! I will post a video over the weekend once I've got the car, which should be Friday 🤞🏼.
I've tried to look at images of the stock calipers to compare, and although they are not that easy to spot as most are behind spokes, as far as I can tell, the calipers are stock.

Thanks guys, I'm less concerned than I was after reading these comments, though I'll still mention it to the selling dealer. It does still have one possible issue though. It's these beauties 🤣 Yes, they really are metallic pink! They are also immaculate and I'm seriously considering keeping them.🤔😂 View attachment 616455
I thought they were red from the first pic. I actually like them and would rock the pink.

This is my new to me R172 55. Picked it up late afternoon yesterday and promptly did about 70 miles just to get a feel! It feels great!
Great spec on the car that I've yet to fully investigate, though the magic sky roof seems like it might be more of a talking point than an actual useful feature, but we'll see.
Looking forward to getting more miles on it and smiles on my face!
