1) Why should people invest in rebuilding their vehicle’s engine’s as opposed to just getting rid of their car?
Rebuilding an engine is an economical option when the engine’s performance is the motivation in seeking a new or used car. Since the rebuilding process basically makes the engine “new” again, you can basically double the mileage you get from the car that you already own. Rebuilding an engine brings the cost per mile driven down drastically. The actual cost per mile benefit has too many individual differences to pin down. Purchase price and miles driven are the key cost variances.
