Enjoy it mate!
I remember going from my 106 xsi to a 1.4 astra and then a Remapped Ibiza Cupra with 200bhp... scared the s**t out of me and my brother overtook me in a Saxo VTR... I was too scared to use the power!
Just get used to it slowly... I killed a Cup a lil while ago in the wet (I just like to add it wasn't my fault "technically" but what evs) and it's devastating.
I'm not even attempting to drive my 172 in this weather... Toyo's are scary enough in the wet... let alone snow! And tbh, it'll be like driving a snow plough so no point!
Have fun with it and take it easy, they're awesome cars with what I think is the perfect power for the chassis and they handle well but you need to know how to drive it... it can go wrong quite easily.
