SAM is a really good school but its hard i know a few people that went there and the that job market is a little dry at the moment as well. and its funny you brought up the hennessy tuner school, its a joke thats all i have to say. I guess if you want to mess around for 6 months (or how ever long it is) then go for it but a friend of mine that i went to wyotech with and just graduated from hennessy said it was a joke and from what else ive heard it is.
The other problem i have with SAM is its such a specific school, theres not alot of carer choices so it can be hard to get a job but when you do its awesome but i still see wyotech as one of the best school, they have the core subjects like uti but the performance end of wyotech blows uti out of the water you learn everything from suspension to turbos to engines (not near as in depth on the engines as SAM) but compared to uti where you put a sbc together and chose from hardly anything to "build it" it really is a joke imo but id check out wyotech before u chose.
Also had a friend that went to san jac hes now a tech at lexus and doing well but there is no aftermarket classes
