His Car needs Repair!

While looking for a car rental few days before our trip to my hometown, my husband and I couldn't decided as to whether we would just have my brother vehicle be repaired instead of renting a car from a rental company. After talking and doing so much research and comparisons, we came to a conclusion to have rent an SUV since it will accommodate more passenger than my brother's car....plus it would really cost us more to have the car repaired. Talking about it, I was wondering how much would it cost my parents in-law to have their rv repair. I bet it would cost like a fortune; don't you think?
