Outdated 1993 small Toyota pick up truck?

I know this isn't the typical tuning car or such but I got a few Qs.
I know that every car has it's limits even if you take best of care of it. Is it best to just invest in a new car before I see the end of this truck or are there other ways to keep this car in better condition ?    

That depends on how much you like your truck, bro. I've seen domestic trucks from the late 80s being redone and restored and they do a pretty good job at it. I don't see why an import truck couldn't have the same TLC as any other. The only concern would be coin, parts availability, mod or not mod, electrical, etc., etc...
You have to decide if it's worth it to you, in the end. The only problem I've seen with late 80s to early 90s imports is rust. They didn't have the greatest metal and the only thing that out lasted the body was the engine. Again, only you can really be the judge of wether or not it's worth restoring. In my oppinion, any import is worth it as long as the desire for some thing different is in your heart. It sounds corny, but it's all about what you want, bro. Have fun with it!

Thanks dude. It's not typical to be seeing us girls on the road with trucks so I for one enjoy cruising around in my small truck. Thanks for everything. I just wanted to keep the V6 engine in but work around the other mods. But I'll stick with stock for now. Thanks a lot.    

I called you "BRO! Sorry about that. I'm used to calling every one that, female or not... You should hear what my sisters say to me when I call them that! He, he! Any way, don't put your self in that category of "JUST A GIRL" or "UNCOMMON FOR A GIRL" comments. If you want it bad enough and you can do some of the work your self or desire to learn, more streangth to you. Never let any one belittle you. Ladies can do every thing a guy can! PERIOD!!! I would love to see what you have dreamed up for the Yota pickup!
