Re: BMW 630i
"Enough" power can only be self defined.
It's not like u're buying the top of the range where u can't choose more powerful options.
If it's "enough", then it implies "satisfaction", which then makes ppl who search for power mods in their vehicle with "enough" performance look like an idiot.
You're paying the bills, so you decide for youself. Go test the car. Good luck with the search.
