    After 18 months of looking at various Esprits, I went up to Wigan and purchased the car you see here. 2 previous owners and 18k on the clock with a full service history based on months and not mileage.

    Its not concours, but it is well above average. The rims have a few scuff marks which I will rectify by having them refinished, or maybe a set of Nova or Futuras when I can afford them.

    A couple of the headlamps have seen the reflective coating deterioate, no doubt to a blocked drain hole.

    The tool kit, sunroof bag and deflector have gone awol as has the battery cover. All will be replaced in due course.

    Not sure if the coolant fans are working either. I will investigate this further. The exhaust also is not square in its mounting.

    The cars condition is reflected by the mileage and apart from a small nick on the centre console leather, the interior is spot on.

    Having owned an S3 Turbo previously, I had been looking for an SE but to no avail. i spent 18 months looking, lots of ropey motors out there. Nice mechanicals, grotty body and vice versa.

    I have got an agreed value policy on the car for a very reasonable �235 fully comp.

    The rear view mirror fell on the drive home. It has cracked around the stem so a replacement will be required. Temperature gauge does not read above 45C. Hoping this is a sensor problem. The aircon also needs a regas.

    August 2005

    I have just purchased the freescan software. So I will ahve a dabble and see whats what!

    Brake light switch has a habit of sticking on at the end of a journey, necessitating a toe under the pedal to bring it home.

    October 2005

    The oil pressure gauge dropped to zero on the way to work. Nearly had heart failure. Fortunately its only a sensor problem.

    January 2006

    Ok, we now have some work in progress:

    Find and repair water leak, around the chargecooler pump.
    Regas the aircon.
    Replace the exhaust mountings, as the rubber block has departed from the metal bracket fixing.
    Get the cooling fans working / replaced, as all 3 are non functioning.
    Replace and change oil to Castrol Rs synthetic.
    Renew oil filter, plugs and air filter.
    Replace juddery wiper blade.
    Sort out low temperature reading on Temp gauge. Possibly the sender unit.
    Fix oil temp warning, due to random working.
    Replace valve caps, because a thieving scrote nicked the others!
    Have a go with freescan.
    Get a touch up stick to rid chips on the nose

    Mmm. Bigger list than I expected, now I have written it down.

    Setember 2006

    Well all the work is completed. Well chuffed. Just finished the engine service, so its ready to go for MOT. Its been nearly a year since ive driven the car. Cant wait. Insurance renewed an MOT booked. Purhased a wind deflector and sunroof bag for �80. Bargain. Also purchased an exterior car cover from Specialised. Nice

    October 2006

    Passed the MOT today with flying colours. New Futura's fitted. Had a fantastic hoon about. All ready for the LEF weekend on the 8th. Cant wait.


    Used the car non stop until Oct 2007. Good as gold all year with good mileage covered. Exhaust manifold has now cracked and needs replacing. This is a horrible job, so the car will taken off the road for the winter and the engine removed.

    The crack is due to the onrush of water from big puddles. Avoid them at all costs or suffer the cracking peril! Dont believe, then try it and let your wallet take the battering.

    I will do a load of other jobs while the car is off the road. Not that anything in particular needs attention. i will do some refurb and subtle upgrades which I will record on here in due course.

    The nose on the car is peppered with fine stone chips again and I will need to find a solution to this!

    This is a fabulous car.

    March 2008

    July 2008
    Flew through the MOT, so happy days. Off to the Silverstone Classic. A few demonstration laps around the track add to the flavour of the weekend.

    Car is running above temp and it looks as though the water pump is leaking.

    Set 2008
    Sure enough, the waterpump needs replacing. Purchased a replacement from SJS for a reasonable �95. Stripped the old and in with the new. Not a bad job actually and much more straight forward than I would have imagined.

    New pump is fine, but compression check shows another issue that could be the headgasket. Number 3 cylinder has evidence of water in it. System is pressurising and compression is low. Off with its head then, but not yet. Bugger.

    Still havent fitted the #6 chip from marcus either. This will have to wait now, until I am satisfied that all is good.

    Brembo upgrade has proved its worth, although the EBC Yellow pads and discs are still bedding in.

    Suspension upgrade is unproven as I have insufficient mileage to comment at present.

    October 2008
    Have applied for Sorn and gearing up to possibly remove engine again to do the head work. Happy days.

    November 2008
    Bought an Elise. Now I can Lotus 24/7. Fabulous. ready to rock n roll on the Esprit then.

    March 2009
    Remove head and replace head gasket. Straight forward task, done with engine in situ. Head and block have been checked for being true and no issues. crack testing also reveals no issues. Cylinder liners are withing tolerance, so on with its head. Replace all gaskets. Replace anti freeze. Change Oil and filter.

    100 miles of restrained running, show normal service is resumed. Like sitting in a big comfy sofa compared to the Elise.

    Im not overtly happy with the new suspension. It feels far too soft, despite being on the hardest settings. I will have to have a tinker with this and optimise the settings on the rebound and pre load.
