    Default Experience with 2007 MS3

    I am new to this forum and am posting a summary of my experience with a 2007 MS3:

    Bought April 2012 in Fort Worth:
    Car had following mods installed by previous owner:
    Tein springs, Injen air intake, Cobb DP, resonators removed, CP-E stage 1 RMM
    Compression check: 170/165/160/154 in June 2012

    Now has 110K miles and has had extensive repairs/updates since bought:
    *All Brake calipers/rotors replaced with new OEM parts
    *Three wheel bearings replaced
    *Left CV axle replaced
    *Tein springs replaced with RaceLand coilovers (junk) replaced with 2010 MS3 OEM springs/shocks
    *Thermostat and water pump replaced
    *Two bent wheels repaired
    *Installed full-time running lights
    *Replaced driver side rear control arm
    *Installed 20" glasspack and AP 3738 muffler (much quieter now)
    *Replaced RaceLands left front strut bearing
    *Clutch replaced
    *Rear O2 sensor replaced
    *Replaced front and rear stabilizer bushings and links (right front stab clamp bolt had broken off and basically had been running over 2 years without front stabilizer bar working)
    *SPC adjustable Camber link installed on rear driver side (Pass side installation is about a 4 hour labor charge due to emissions canister blocking removal of non-adjustable OEM camber link bolt. Used GM part number from Amazon "ACDelco 45K0187..." )
    *Installed RMM ("6068A CM5Z-6068A 13-14 Ford Focus Electric").
    *Installed BECK/ARNLEY PMM

    All together about $7K in repairs/upgrades over past 3 years.

    Remaining tasks:
    Replace timing chain
    Decarbonize intake valves
    Install new sparkplugs
    Replace trans fluid with Motorcraft MTX-75 & IB5 XT-M5-QS
    Use AP2 to tune for high altitude (5000ft) operation (only abt 12 psi max boost now)
    Figure out how to install pass side adjustable camber link at a reasonable cost.
    Attack NVH with sound deadening as last resort

    In summary, a lot has been learned about what NOT to do in buying an MS3. If buying an MS3 today I would buy one that is totally stock, under 40K miles, and owned by a little ol' lady school teacher. (I also own a '94 turboed Miata that has only had oil/anti-freeze changes the past 12 years) This MS3 has been a very high maintenance bitch that I wouldn't care to repeat. But, it reminds me so much of the '58 Volvo 444's handling and feel I used to have that I will not now give up this MS3-

    My experience has been nothing but great. I purchased my 2007 MS3 new and couldn't be happier with the car. It's been very reliable, quick, fun to drive and manages to still have decent fuel economy. I have done a few upgrades to personalize the car to my liking. Bilstein sport shocks and struts, Vibrant exhaust, Cobb Air Box and Intake, TIP, wider gas pedal to aid in heel and toe, light weight forged wheels for better ride, handling, braking and acceleration. I just hit 100,000kms and look forward to driving every time.
    Sorry you are having so many problems with yours.
