I'm still not 100% sure I'm doing the right thing here, but here goes.....

I bought my Moon Grey Plus in July 2010 with just 24,500 miles on it, after my previous Sprint Blue succumbed to rust. Mechanically, the Sprinty was 100%, so all the modified parts were transferred over to the Moonie. I then proceeded to use it as a daily driver for three more years until I realised the costs were too high (I was doing 20,000 miles a year). In 2013 I retired it as a daily driver and used it for weekends and occasional blasts. It is now down to about 1,000 miles a year.

This is surely one of the best-known and best-resolved Coupes on the forum. The way it is now is the result of seven years development in the Sprint Blue and another five years with the Moonie. I set out to create the quickest Coupe in the country (note, not the fastest or the most powerful) by blending huge power with sublime handling and good grip and traction. Those that have been around the forum long enough will know how much effort has gone into this car - stuff like the subframe brace and the Brembo two-piece floating discs are just a couple of examples of me spending time and money to make significant improvements to the car.

Put quite simply:-
  • It will potter around town quite happily
  • It will cruise on the motorway in (relative) comfort
  • It will return 34mpg fully loaded on a cruise to LeMans and back
  • It will run a standing quarter mile in less than 12.5 seconds
  • It will do 0-100 in about 9.5 seconds
  • More impressively, it will do 60-120 in about 7.5 seconds
  • top speed is "unknown", but estimated at 180-190 if I could ever find anywhere long enough to try

The basic details:

1999 Moon Grey 20 valve Turbo Plus
Usual Plus extras such as red-stitched leather Recaros, white clocks, boot nets etc
About 83,000 miles
MOT to March 2019
Full service history, although its due a service and a cambelt right now

Condition - 9/10. It was actually VERY good until I did a charity track day at Bruntingthorpe, during which it got a strong dose of gravel-rash from tailing exotica at 160mph. The front end in particular is looking tired - the front bumper and bonnet are pretty badly stone-chipped and will require paint to correct. The leading edge of the bonnet is bubbling slightly, but is easily catchable. One of the side-skirts has a scuff. One of the rear light rings is bubbling slightly. There are a few very minor parking dings. All of these defects are nothing untoward for a 19 year old car with 83k on it.

Along with all the other odds and sods, that's about 13,000 in parts alone. I conservatively estimate that the labour bill (Mostly Motormech) for all the above is at least another 10,000

It has been suggested that I'll make more money by breaking the car for the tuning parts - not a chance! - I want this car to go to someone who will carry on throwing the attention (and money) at it that I've done over the years

To give you an idea of the effort that went into the engine build - standard Coupe 20VT rod and piston assemblies are balanced to within 20 grams of each other. Paul balanced the Accralite pistons and Cunningham rods to within 0.5 grams. Its attention to detail like this that makes the difference between a powerful Coupe and a one with reliable power.

The result of all the engine mods is a peak of 488bhp at 7,200rpm using 1.6 bar (raised rev limiter due to the balanced internals). Torque was 378 lb-ft at 6,200 rpm. The car briefly made over 500bhp on the dyno, but this was a bit close to the limit, so it was backed off to something that would be reliable.

Its also making 200bhp at 4,000rpm, 300bhp at 4,750rpm and 400bhp at 5,600rpm

A gauge of the performance is that at Bruntingthorpe, it pulled away from an Audi RS6 C5, a Porsche 911 GT3 and an early Nissan GTR (admittedly, the GT3 whupped my ass round the corners...)

The handling has to be experienced to be believed. With the Quaife diff, it corners like a RWD car - just feed it in and when the understeer starts, feed in more power and it just pulls round. I've had many positive comments from drivers of fairly exotic stuff about just how well it handles. The chassis spec is the same as the Sprint Blue, in which I won the FWD handling class at Ten of the Best two years running.

Other than the paintwork issues I've mentioned above, the only negatives I can think of are:-
  • Aircon not working - it was working when I laid it up for winter, so almost certainly just needs a re-gas
  • Tyres are, well, tired. They are Toyo T1-R and they are four years old. It really needs something better - if I keep the car, I'll fit Yoko AD08R or Toyo R1-R
  • There are a few squeaks and rattles - just can't be bothered to track them down
  • Cold start can be a pain - it needs 30-60 seconds without touching the throttle before it can be driven away without a misfire - could ideally do with a bit more mapping to smooth it out.

I've also spent a lot of time and effort making the car look close to standard and as comfortable as possible. For example, the entire interior is covered in self-adhesive closed-cell foam to dampen the general road noise. The sound system is very well-sorted, with great speakers, a subtle flat sub in the boot and very crisp and clear sound.

By separate negotiation, I can also include a substantial stock of spares, including:-
  • brand-new OE Plus cam cover - never been fitted
  • Set of OE plus wheels - freshly refurbed - never had tyres fitted
  • Three large boxes of various parts - ECU and lock-set, spare lights, loads of interior plastics and other hard-to-get bits

So - the hard bit - price....

With good paint, I reckon a Coupe with this much performance is worth 15k all day long. Heck, there are standard Coupes (with admittedly better paintwork) fetching 10k

So - taking the fact that it needs paint into account, I've set the price accordingly at 10,995. I've had a quote for 2k for a complete respray (by the chap that's done loads of Coupes over the years, including an Auto Italia concours winner)

Weirdly, I have very few photos of the car - here's three that I can lay my hands on


Note - the final image has been doctored to clean up some of the stone-chips

There's LOADS more I can tell to anyone that's interested - I'm happy to possible buyers a passenger ride and even a drive on proof of insurance (and the understanding that if you break it, you buy it!)

Oh God - what am I doing?......

Final caveat - I might get cold feet and withdraw from the sale when I come to my senses

EDIt - Price reduction to 10,995 and some more photos
