Congrats on the purchase! You made a very good choice. I came from a smaller car too but the first time i drove the car back from the dealership it felt like I had been driving if for ages. It's surprisingly very easy to get used to, as it will happily drive in docile mode as it would at defcon 5

Its quite funny actually - drive the smaller car around a bend quickly and there's so much going on (body roll, engine revs, stuff flying everywhere (including yourself), tyres screaching). Drive this car around the same bend at the same speed and everything is calm, peaceful and collected.
