As for trading it in though the missions may be short (i'm only half way through) i'll never get bored of driving at uber high speed down the long strip on the 2nd island going over the ramp and just smashing into things and blowing things up

Explosions look mint on this i think.
Just managed to do that old hospital mission at the 4th attempt. Planned my escape route, just legged it through the building to the nearest vehicle which was shot to pieces within seconds, somehow managed to get away but ended up trapped in a mini park with only 3 tyres left

. Luckboxed my way out of the area, then somehow got across to the other island and to a pay&spray with only 3 tires and 3* wanted level the whole way
Another funny thing i found the other day was when i slightly crashed into a normal looking car on the first island and all of a sudden two dudes got out with AK47's and shot my to pieces

Must have been under cover cops or mafioso!
