I had an S-10 and an S-15, both with the incredibly easy to work on 258 6, and both 4WD. These were both great, dependable trucks. Good off-road. An 89 and a 92.
Actually I can't say a bad thing about them.
But it is so very true that you can outgrow an S10. After my S10 and S15...I got my first Jeep--10 years ago. After that I never looked back. Have fun!
