2008 Suzuki Vitara new car that's 1.5 years old

I just purchaced a Grand Vitara that was a leftover from 2008. It was the right car for me and my family but i'm a little concerned because it has been sitting on the dealers lot for 1.5 years. Is there anything I should be xtra concerned about as far as long term realibility and maintence cost. All factory warranty is in effect so repairs should be covered but I want to make sure my thrifty ways didn't guarantee I bought a lemon.
