In a lucid dream if you can imagine it, you can do it, so yes it's definitely possible 
Like with a lot of stuff related to lucid dreaming, I think how long it takes to have good dream control is different for everybody. You seem to have pretty good dream control already, summoning a dirt bike, changing appearance, and becoming invisible is great for your first LD! (^^)b
Lucid dreams can definitely be as vivid as waking life and like TwitchLucidity said, you don't need to have had a bunch of lucids to have a life like one. You can do a lot of things to increase dream vividness, dream journaling, getting enough sleep, immersing yourself within the dream, etc. LDs can be 40+ minutes, but even if it's 5 minutes that's still enough to have an awesome experience.
You seem to already have a good start so just keep practicing and it'll all come together ^_^
