Minnehaha — A Vancouver automotive repair shop is lending a hand to single parents by giving 100 of them free oil changes and safety inspections this month. It’s the fourth year in a row that Just Right Auto Repair and owner Shari Troyer have offered to help single parents, who might appreciate a way to save money on car maintenance. Parents signed up last month to take advantage of the offer, which the shop estimates is worth a total of about $13,750, including the value of raffle prizes that will be awarded at the end of this month. “What we are offering is a very small thing, but if we can all pitch in and help, it can make a difference in the lives of people who are raising our future generations,” Troyer said in a press release.
