the best scopes take up at least the back seat of the car
but what you have is a pretty standard scope and shouldnt be too heavy. the good thing is that given that it is an alt az mount (just a guess) and a refractor, you can pretty much set it up and start observing. no need for collimating optics, polar aligning or even getting a perfectly level set up. what you will need to do is get a planisphere or download some planetarium app on your tablet/phone to see what objects are up. try to get some views of the moon (when it comes a bit higher in the sky), the Orion Nebula, Jupiter (later at night) and its moons. you can also look at binary stars. spend some time learning the constellations and navigating the sky. you also might want to go to some kind of star party and meet up with people who can show you the ropes.
