the doors do not open but is very easy to get into. the viper also climbs just about anything the jeep power wheels climb in some aspects i think it does better on climbing. he goes through grass, sand, over tree branches and even up small rock piles great fun for the little ones

I lost my charger - but, I found this company - I haven't ordered it yet - but, if I don't come across the charger in a day or two - this is where I will get it from:

It's the - 12 Volt Pacific Cycle Kid Trax Battery Charger

I think it's alittle expensive for a charger - that's why I am still looking for mine - but, I might have to resort to this one...

Good luck.
