I've been through this with a relative and regret it. The knowledge gained and paid for (not by him) was/is essentially wasted. So it was a bad investment.
The "job project" should have started with a local survey of what the graduates can expect to make, what benefits they will receive and what their career prospects are both initially and over the years.
It would also be valuable to know what the turnover rate is for each dealership and the major reasons why they left.
With the dealership making $100+ per labor hour, technicians are lucky to see much more than minimum wage. Net, net, you can't raise a family on that. So many very qualified technicians leave the trade.
My point is be sure you have done your homework up front so you aren't disappointed in the end.
To be clear, I have no issue with MMI, their programs and support systems for housing--etc. It's the transition into the real world where a decent compensation package would go a long way toward long term employee retention.
For those who have a background in management and labor cost it comes as no surprise that planned turnover can keep rising labor costs down. especially if the new hires meet accepted standards and are will to work at minimum wage.
BTW: This is a sigificant component in why we see so many service complaints as well.
