You did the right thing to walk away from the purchase. With a relatively high mileage car you need to have complete confidence in its history otherwise it will burn you. I recently had to have 2 throttle actuators replaced luckily under warranty as the parts cost alone was insane. So do your homework before you purchase, it will benefit you immensely in the long run to get a dealership warranty covered car. I wouldn't buy an E92 M3 without going over it with a fine tooth comb.
Performance/usability wise it is a fantastic machine, very usable as a daily driver and has a fantastically capable chassis. IMHO I cant understand people who think the car is sluggish, numb and lifeless, they obviously haven't had the opportunity to exploit its performance. Yes around town in low revs it can feel 'heavy' at times but that's the beauty of it and reflects its usability as a daily driver. The E92 M3 has to be driven, if your a person who wants to potter a
bout and have a car that flatters your driving its not for you, you will not get the most out of the engine or chassis.
People often forget the development that goes into an M3, thinking its just a tweaked 3 series, the below is quite a nice insight. Absolutely without doubt one of the best v8 coupes ever.

OP not sure if you've 100% decided on an E92 M3 but you won't be disappointed.
I've driven many E46's M3's here and more in Germany. I also take mine from the UK to Germany at least twice a month.
For cruising or out and out speed/comfort it's very hard to beat.
Seek out a good dealer for a Manual and an M DCT, ask to set the M mode up and go for a proper blast. It's not just the Engine. The suspension/Handling is on another level
