l did not order splash guards from the dealer because l thought the price was a rip-off. Now I am having second thoughts and am considering ordering them from the Internet. Could l install myself or would l have to hire an auto mechanic?

you could probably do it yourself contact the website you are ordering from and ask them.

yes it is possible, not very hard either as long as you want to take the time to do it. l reccomend having a dealership do it though because its not too expensive, faster, and if they accidently break something its on them not you.
