I am not really an expert about cars but hubby knows a lot about it. This is one of the advantages when our cars have problems or there are car parts that need to be replaced. He is doing it himself and it truly save us some money. I can still remember when the replaced the gas spring of his Volkwagen car sometime in 2005. He just ordered the parts and did it in his brother-in-law who owns a car repair shop. He can use all the tools and equipments there for free. Sometimes his s twin sister’s husband is the one who orders the parts or any accessories that he needs for our two cars.
