I've used these services on occasion and generally had good experiences. I often wonder if it is a straightforward equation to quantify profitability with all the variables involved with using a personal vehicle. I had a driver lament to me that the high mileage has caused rapid depreciation on his vehicle and that the trade value is much less than the loan balance. It seems to me that one would need to perform due diligence and have basic financial acumen before pursuing this gig. Wondering if anybody here has tried it and what the experience has been.
