lmao at brianR he may drive a porsche but he speaks the bloody truth
also take on Has's advise. Some of the mods on my car cost me a fortune to insure and with you only being 17, you really should check the fleet covers mods, because in my experience it never does.
imo, if your gonna tint the windows you need it done professionally for around 250 quid mark, and no more than a light tint or it looks like a van. If it was me i'd just enjoy the car for the time being, and get used to driving it
