Personal opinion. If I'm getting a 328, I rather get one which is stock rather than heavily modded i.e. bodykit, gigantic rims, etc. At least if the car is stock, there is a lower chance the owner thrashes the car. Then again, how do you define 'thrash' or 'whack'? Being driven fast definitely doesn't equal to these 2 terms.
Driving it fast or giving it the little push it very much deserves is considered a norm. In fact it's healthy for the engine. Even if you buy an M3 that hardly exceeds 120km/h most of the time, it doesn't mean the car is tip top because the engine's capacity has been under-utilised.
I know quite a number of people whose 328 has genuine low mileage because it's either used as the 2nd or 3rd car. When this is the case, it mean the owner has no problems maintaining the car. I've seen 1995 328s with only 80-90k on the clock. And this is genuine.
My 2 cents - get a stock standard car and slowly mod till your heart content later on.
Be creative rather than assuming other people's identity. Hahahah....
