I bought this car several weeks ago and I've loved every day I've owned it, while behind the wheel, at work but secretly planning improvements, or just getting my hands dirty underneath it.
It was a fairly clean example of a low-milage 2004 Mercedes but it still had the usual vices expected of a car kept in wet climates and around busy streets:
Paint de-lamination on panel edges, surface rust across most exposed metal components, a couple of tiny door dings, long overdue for a real service... the usual stuff.
In this time I've made the following modifications:
Bought a private plate
Front grille swapped for split bar design and 85mm front badge
16 inch Borbet 5 spoke (split) wheels with Merc center caps
Falken Z rated tires
Broke back and painted original calipers
EBC Redstuff pads
Window tinted black to maximum legal limit (Limo rear and quarters, 75% light pass on sides)
Halo ring lamp units (E-marked and road legal)
Black Diamond G12 vented front and rear brake discs
Back box/secondary cat deletion, replaced with lightweight pipe and 4 inch tip
K&N cone filter and superior air induction kit
Performance-oriented ECU remap and rev limiter removal
Supercharger pulley kit
Fiberglass VMAX hood
Fiberglass VMAX wings
I'll continue to update this thread with pictures and later work. It'll help keep me organised, busy and out of trouble if nothing else.
I've owned much heavier V6 cars in the past and I'm enjoying taking a smaller (but much lighter) 4 cylinder in-line in this direction. Any advice on bugbears, things to avoid, or just general waffle from more experienced SLK owners is of course welcome.
Have a good week.
