Out of interest, what do you think you will advertise it at?

Just curious really as I have a 997.1 GT3 with fatty bum bum seats and PCCB's but with a little more mileage than yours (as a side note, my car has NO over revs in any rev range)
Colour and Warranty?

I could do with the fatty bum seats - my ass is way too big for the carbon buckets.

No over revs is quite rare, I'm led to believe by the independents I've spoken to. I'll be advertising it this weekend, so wait and see!

It will be more than I've been offered by Porsche and Indy's, that's for sure.

Pete - I've been told by a very well respected independent - 'you could drive the GT3 round the track all day bouncing off the rev limited and it won't register any over revs'.

However, if the driver changes from 5th to 2nd, it'll probably register an over rev.

The limiter prevents over revs on the up change, not the down change.

This is the way I understand it anyway.

The rev limiter protects the engine and is not damaging, although it is not a good idea to habitually bounce off it. Over revving is much worse. It happens when you e.g. go screaming into a corner, miss a gear by mistake going from say 5th to 3rd and force the engine to rev above the normal safe revving parameter (as set out by Porsche for any given engine).

Colour is GT Silver (very vanilla but I like it) and the warranty ran out three weeks ago... I didn't renew it.

We are thinking along the same lines Soov535 be interesting to know what sort of discount he bought the car for if at all. Also agreed if it has a Porsche warranty then all well and good until the warranty expires or the car is to old to warranty
What difference does it make how much I bought the car for 15 months ago?

I bought it from a main dealer as a warranted, low mileage, rare coloured, club sport spec - I can tell you now that they weren't offering much in the way of discount! They did throw in a replacement front splitter and quite a few cups of coffee.

They want to buy it back - doesn't that speak volumes, or am I being completely naive?

I've bought a lot of sports cars from main dealers and independents - I can honestly say that Porsche have been by far and away the best of the bunch.

When the warranty expires, you just pay to have another one put on it - isn't that the way everyone does it? I can't comment on how the car will be driven by the next owner, so if they over rev it then they need to heed the consequences - Porsche are unlikely to warrant a car that's been over revved in the last 100 hours - that's what the technician said to me this morning.

Really nice colour - I like. Why don't you get a warranty on it? If you don't mind me asking.

only things which go wrong are not covered , engine is strong as an ox

every thing else fails but most of it is classed as consumables

Not a good idea to habitually bounce off it, but nevertheless untraceable.

Over revs are very common, but agree'd not ideal. If they've happened recently (last 50 hours) than if I was a buyer and not a seller I'd be asking for a compression test and would really want a porsche warranty (unless I could get the car for £50k!).

Over rev 600 hours ago....... Please tell me you see the point I'm trying to make with this post - if the engine was going to go 'pop', it would have within 20/30 hours of the over rev. 600 hours on, and a compression test later, the car drives as if it only has 23,000 miles on the clock, which is exactly what it has on the clock.

My old 997 C2S had the baffle go on the sports exhaust - luckily, under warranty. £2000.

As food for thought ; How much would you expect the difference to be between a perfect example car and a car [like yours] showing a RR4 on the engine ?
Lets just say it's £10k difference : How much would an OPC charge to rebuild the engine and clear the issue completely ?
If there's an alpha difference, then surely this is the answer. Not only that, but a car with a recent Porsche Warranted rebuild is likely to fetch a better figure, no ?

The car you have has grown in value massively over the last 18months or so, and as such, is attracting a broader spectrum of buyers as the higher values have put them into the radar of the speculator market as well as the geeky enthusiasts that have typically coveted GT3's and are likely to be more aware of RR issues

Unfortunately, the RR issue has reduced in profile (on PH, certainly) recently, but threads like this only serve to perpetuate the problem

How many manual sports cars over the years have been massively over revved, but it's gone unrecorded, and hence people buy unaware and unbothered by a history that might not cause any problems whatsoever down the line.

From what I've learnt this week, I don't think that the difference in value between a 'holy grail' and mine is quite as much as £10k. The market is strong enough to absorb the whole over rev thing - my post only goes to highlight how many genuine enthusiasts actually listen to the advice of the main dealers and independents (who inevitably are ex-Porsche technicians) - car's that have been over revved a significant period of time ago aren't deemed as an issue. One of the guys at Solihull Porsche suggested that the issue is something that Porsche themselves highlighted following an individual case where an engine (warranted car) was over revved and then blew up - but hey, there are many marques out there that have been thrashed and then subsequently blown up, not just GT3's.

IMO, It's not worth the money. I would rather put the cash aside and/or spend the cash on other things.

Having said that though, the warranty it had when I bought it covered a new condenser for the air conditioning system (£unknown) and a new amplifier for the stereo (£700) and this was when the car was running the following:

Michelin Super Sport tyres
RSS Engine mounts
Hayward and Scott bypass exhaust
Techart front shock top mounts
997.2 RS rear brake cooling ducts
BMC Air filter

So in my experience, the warranty is not as 'restrictive' as some claim it to be and you can get warranty work done if you have made modifications.

As a side note, I think the next steps for me with this car are the following:

exe-tc single way suspension
997 GT3 rally car LSD
RSS coffin arms and dog links

and when funds allow....

3.9l engine conversion

OP if you read the question properly its asking IF you bought the car for a discount relative to others at the time and there was no mention of asking what you paid for it!

YOu didn't offer that information in the original post so in order to understand a little more of the history and give you a realistic price comparison its not unrealistic to ask.

Sounds like the car is a goodun anyhow as the OPC will buy it back and it has a current warranty. Wonder if they will give you more than you paid for it though? Others as you have highlighted have risen considerably in the last 15 months

in my ownership i have bounced it of the limiter when overtaking maybe two or three times, just curious as whether i've racked up more RR1's or not.
i'll probably get them to do me a DME report when i have it serviced next, the results should be interesting as i have definitely not pissed up a downshift.

Looks lovely, kind of 996-retro too to my eyes.


I can't believe anyone's suggesting the value should be lower....

1) IT WAS UNDER 1/10th (ONE TENTH) OF A SECOND
2) THERE ARE 6 RANGES - IT ONLY GOT TO NUMBER 4
3) IT WAS 600 (SIX HUNDRED) HOURS AGO
4) IT WAS UNDER 1/10TH OF A SECOND
5) PORSCHE SOLD IT LIKE THAT, CLEAN BILL OF HEALTH
6) IT WAS UNDER 1/10TH OF A SECOND


I'd venture to suggest that cars with no rev ranges whatsoever (i.e. even range 1, at/everso slightly over the limiter) are more of a risk as they show no evidence of having been exercised properly - would you want to take the risk on an engine that may never have been above 5,000 rpm?
