330+ per hour is not bad, if theres a set price for repairs, even better. popping and replacing ball joints versus the whole control arm is cheaper, cutting rotors, mixing parts from other cars, if its a solid repair, it will work.
A person can even kick back and have a small crew or honest mechanic willing to take on regular work out of his shop, and just bankroll, manage the operation and "Eat". Old Monteroes, 4 dr pick ups, honda accords, and siennas still sell well and are very popular. You can pick up any auto with a great reliability record and the people know it will be running good for a few years. A fresh helping of lubricants, at times , is all the viagra a used car might need to get a new start.
the much older cars, pre 79' are still on the road in above average shape. I ve been in a few in the DR that easily have over 300,000 miles on the same motor and clutch. Those owners would take care of their cars, and those DR mechanics in the country side take their work serious.
theres gotta be a group of people in the DR that have enough income to get something a little more than a scooter, but not enough for a new or 4 year old car. just looking at the asking price of some of these beaters online, im sure there would be some intrest from the public.
