I've had the 07 speed3 since July 09 and I have done everything I could for reliability and maintenance you can think of (shy of cleaning the valves as I think what everyone does is overrated and easier things can be done).
Here's what I've done so far:
Car has ~125K and ALL maint. is done and has been since 68K when I bought the car.
I have some upgrades done to it (to preserve it) than for power.
Car has been tastefully modified and here is what has been done(under MY possesion). Car was stock when I bought it.
Brakes: EBC red brake pads (110K)
Brakes: Centric HD rotors (110K)
OEM thermostat: (OEM) at 115-117K
Battery replaced at 110K (AZ Gold 09/12)
Front driver axle replaced at 124K
Water pump OEM at ~100K
Many a sets of plugs,last at (118K) NGK6510's
Radiator flushed yearly (70K,90K,100K) and then at 117K when I did the thermostat
Flushed gearbox with OEM fluid at 70K and then the FoMoCo at 71K (didn't like that feel at 71K). Still feels smooth as butter after 50K+
This is something I take EXTREME pride in: OCI's done with Pennz Ultra & Plat every 2800-3000K religiously.
Brake fluid flushed at 72K and 100K.
PS fluid: done at 80K-115K and have always siphoned and filled (turkey baster method) with OEM fluid.
Seafoamed every 1K-2K from 70K-105K and then every OCI afterwards.
FP internals cleaned at 112K
PCV at 93-94K (see below)
OEM rear endlinks at 74-75K
OEM Bose stereo at 118-119K (cannot reset time correctly) since then
BFG KDW'2 replaced at 92K
OEM wheels/Rims replaced at 93K (Enkei FLC-01 Matte Bronze 18x7.5 +53). Have one extra due to a DT fuckup on install not knowing 5x100 and 5x114.5 difference
Lamin-X on front headlights and fogs 121K (orig headlights replaced at 95K)
Thermostat changed at 118K
Here are the mods:
CP-E TMIC installed at 98K

Fumoto drain valve at 68K
NGK (6510's) installed at 115K (changed every 5-10K due to SF'ing)
Eibach ProKit at the same time as above and assume the same mileage
COBB SRI at 71K (cleaned filter every 3-6K)

Omori Electronic boost gauge installed at 80K (4 yrs old at that time and is spot on from AP)
JBR AP mount
CS airbox for COBB SRI installed at 71K
Here is the link to COBB Plano where it was tuned twice by Calvin First one here: http://www.cobbtuning.com/Dyno-Database-s/70119.htm

Second tune with TMIC, CB, plugs, DP, boost tubes came out to 300/355
