Generally more reliable, blinged out and cheaper in petrol and interest (you’ll get a better rate). But they lose value the second you drive ’em out the showroom.
Less pricey with lower insurance rates, but long-term might need more time in the shop and it may not have a warranty.
Going somewhere for a short stay? It’s smart to rent. Otherwise, not so much: you only get a certain number of kilometres and it costs big to back out.
