OK so the coupes (assuming not M, not at that price anyway) will have the 3.0si engine. Early ones (like mine) have a magnesium valve Cover, this changed to plastic in late 07 I believe.
Main things that will go around the 100k mark are, coolant expansion tank (cheap and easy), most of the suspension may well need replacing (especially if lowering springs fitted on orig shocks), bilstein b12 kit is a great replacement, and use meyle HD for top mounts etc.
Lower arms with bushes and ball joints and droplinks are cheap enough and easy diy, will massively improve the ride.
Gearbox and diff oil need doing if not done before (huge change to gear shift feel). Full service obviously, easy and cheap DIY job. Lifter tick is cured by warning the engine up and sitting at 3k rpm for 3 min, this is what bmw do with them if customer complains. The ccv system can clog, cheap enough for parts but a good hrs DIY job. Wheel speed sensors and hubs may need doing and remember that most of the bolts are aluminium so have to be replaced once removed (generally cheap enough from BMW).
Alternator belts and pulleys are cheap and 30 min DIY job (do at the same time as the expansion tank).
I would also highly recommend getting a dcan cable and a copy of inpa, dis v57 and sss v32 as they will save you a fortune in diagnostic costs and calibration etc.
Vanos solenoids can fail, use genuine ones only Chinese ones cause more issues than they are worth.
I also recommend replacing the guebo (propshaft coupler).
And if run flats are still fitted then look into replacing them for non rfts as owners report crap handling and ride with them fitted, rfts on 19s usually lead to cracked rims too.
