I am 2 for 2 with the bolt heads snapping off during spark plug changes, and I am a bit hesitant to change the plugs in my other two smart cars. If your not too busy I can let you remove the bolts on the next 2, maybe you will have better luck than me.

Actually SS bolts in aluminum is not a good idea. Take a look at any galvanic series chart of metals to see why.
https://en.wikipedia.org/wiki/Galvanic_series
https://www.corrosionpedia.com/an-in...rrosion/2/1403

Aluminum being the less noble metal than SS it will corrode, especially so, given the large potential difference between the two metals. I'd recommend using a zinc-plated fastener as the zinc is closer to aluminum on the galvanic series so the combination is less prone to corrosion. Additionally in this case the zinc becomes the sacrificial anode, not the aluminum.

There is a reason that manufacturers' use zinc-plated fasteners with aluminum. If you must use SS, apply an anti-seize compound, preferably one containing zinc.

I put copper anti seize on the bolts, and spark plug threads.

I also soaked the bolt in Pb Blaster (used a q-tip to apply) daily for two weeks, before trying to remove...
