Been using my dads Samsung nx5 for cars meets etc but want to get something for myself

Something that is easy to use but with the right lens etc will take sweet pics

Am I best of getting a brand new one or looking 2nd hand?
Guessing Nikon or canon? Think I prefer the Nikon, my sister has one and I really liked it

Looking to spend say up to £500 plus new lens and any other extras
Will mainly be for car meets, holiday then odd wedding, family occasions etc.
Thanks any tips welcome
