M3 engire problems were to a very specific model, and was fixed pretty quickely.
My Parents owned/haveowned 4 BMW's and had absoulite 0 problems with any of them, and that include autocrossing one a lot, BMW are great cars, I have not seen one in the last 10 years that has had any major electrical problems, but when they do break it is going to more expensice than a honda, but hell most bmw's cost more than 2 hondas.
