Just to add - I am a huge fan of PETG. It strings more than PLA but has better heat resistance and is stronger. Also I've heard for vehicle parts, ASA is the way to go. It is UV resistant, and has a lot of the advantages of ABS but with way less drawbacks. I haven't printed with ASA yet myself though.
Yeah, PETG is really nice, especially because it is more elastic. I.e. it doesn't fail suddenly but more like gradually and can even recover a little!
The only issue with PETG and ASA is that they require higher temps. In my experience with PETG, I was able to achieve good results with what I had only with 250C. ASA as far as I remember requires even higher temp like 260C.. and they both love hotter bases (80-100C). Most of PLA+ what I print is 210C nozzle and 40-45C base..
If you need some higher temp resistance then PLA is not the best choice.. Regarding the UV resistance.. when I started, I thought that PLA will go bad outside just in a couple of months.. turned out I was wrong.. I even printed a lot of different hooks/small things for my family's camping gear.
Another thing, when I started, I truly believed that ABS is stronger than PLA. Turns out, this is just a myth.. different materials behave differently under static and dynamic load and nowadays ABS is not my first choice.. damn, even PLA from different manufacturers have quite different properties and require different print settings. For example, I have white PLA that just doesn't stick properly if the base is less than 45C. But my most used black one sticks nicely at 40C and can work even with 35C.
Also, if you want to print ABS/ASA - I would strongly recommend using an enclosure for your printer and good ventilation. ABS emits some nasty fumes that I personally wouldn't want to breathe (ASA is better in this aspect but still). I actually close the door and leave the room when printing ABS. At the same time, I print PLA right next to my table (my printer has an enclosure, so it helps to minimize fumes).
I like material tests from CNC Kitchen:

EDIT: heh, sorry for a long reply, but I hope that this info will help someone who may be just starting to play with 3d printing
