Bought the S10 in the fall of 1994 because I just relocated to Northeastern Ohio and I needed four wheel drive for the winter. I have never been left stranded by this truck and beyond routine maintenance I have had no repair issues. I would recommend these trucks to anyone.
I like the 4.3l engine and shift on the fly four wheel drive. Gas mileage is not too back I average 21 on longer trips with reasonable speeds.
I'd like a bit more legroom, but I'm 6'3" and it can be a common complaint for me in full size trucks too.
I love my S10. It has never given me any mechanical problems except sensors and the fuel pump, but being 14 yrs old and having 178000 miles, I think that is excellent! There is very little rust and I live in the north east. The mileage is at best 16mpg on the road, around town its about 12mpg. This truck has only left me stranded once, that is when the fuel pump went. The truck is fantastic in the mud and has a very comfortable ride
I don't have one favorite feature, I love the whole truck.
