If you do any car work at all on your own (or if you have a good friend or relative who is good with cars), search this site and the web for things called “Quick Struts” - they make this a reasonable DIY job. If you don’t mess with cars very much don’t try it though.
Although 106K is not an unreasonable time to need struts, what you really need to do though is answer texases questions. If you put the phrase “you need new struts” through a Mechanic to English translator I believe the literal translation comes out to be “we have been slow and are trying to boost business.” Be especially suspicious if they also offered to change your tail light fluid and filter.
