To anyone that's looking to get into wrenching on your own stuff, I can definitely recommend getting started on a motorcycle if you have space, money or time constraints. It's a lot more accessible initially.
The LX platform is incredibly easy to work on. Rear wheel drive, nothing too complicated to understand, good parts availability from places like Rock Auto. The big Hemi 5.7 is easy to rebuild and very rewarding. I grew up working on small japanese cars and Alfa Romeos, the Hemi reminds me a lot of the Alfa "Nord" engine despite the pushrods.
I had an MX-5 and loved it, but the LX cars are affordable muscle cars that even a modest workshop can make something fun out of.
As for what bike might be interesting, I bought a fuel injected, single cylinder bike. Pretty much as simple as it gets, and a great way to get started with the basics.
Don't be afraid to jump in, you'll be surprised at how easy it comes to you.
