Why? Well I cant give you an exact opinion for wyo-tech, because I didnt go there. But I did go through the full UTI program, and I dont have any reason to doubt that wyo-tech would be any different.
For starters, the hands on training was practically USELESS. The only "cars" they had for you to work on were for the electric/diag classes. Anything that had to do with suspension/exhaust/brakes (basically anything mechanical), had to be done on a students car, so they basically did the work. In other words, if you have no experience replacing any type of suspension components or servicing brakes, you likely wont have any more knowlege once you've finished the course.
The "books" they provided us were nothing more than powerpoint presentation printouts. I had several instructors who NEVER even worked on cars, they were just "certified" in the class they taught. Many of them were terrible at best communicating the information, and classes tended to be long, drawn out, and boring. Not exactly the best environment for retaining alot of information.
For all the manufacturer programs, yes they are huge perks, but there is alot that goes behind getting in. I lost my 4.0GPA to one class (graduated with a 3.9GPA) and standed no chance in getting into any programs. My attendance was at 95% when I graduated, most of the programs required 98% minimum. Alot of them say they only require a 98%, but in reality you need a 99% or perfect. A good attendance rate was hard as hell to get, probably one of the most difficult things of the entire program. Everything was on a 15min basis, so if you were even 1 min late, you got docked for .25hrs (15mins). This adds up FAST. UTI provides no housing, or any type of housing allowance, so I was forced to spend most of any time I had after school, at work. Not really any choice in the matter. Get used to being tired.
As for "performance" classes...at UTI forget it. They have some flashy cars in there to work on sure, but you dont do much with them. We had a supra, SRT4, a mustang GT with a vortech blower, just to name a few. The mustang was limited to 6psi (yea...fun). The only "mods" you got to do was intake and exhaust. And those parts they already had...you dont get to go order things you want to put on the car. Some of the intakes were made out of PVC piping, and on some of the cars the only exhaust mod you could do was disconnecting the stock exhaust cause they didnt have any kits for them.
What it all comes down to is the school reps lie alot...an unbelieveable alot. If you want to work on cars, what I would recommend doing is go through a community college program or 4 year school if you must, get an associates degree in automotive technology and go to work. If you work at a dealer, they will send you to school anyway. Im down 22k in tuition, and of all the job interviews i've been to, they didnt care about the school, just any past experience I had.
