Good Garage and itv testing

There is one in San Javier and San Pedro, I've used both and they are very helpful and I didn't have a Cita previa but went straight through the one in San Javier is just off the Balsicas road behind fuel station on the right heading towards the AP7, and the 1 in San Pedro is just off 332 on the left on the ind estate heading towards Pillar de la Horadada, you can Google both of them.

MjMechanics Formentera, 15, San Javier - google them or FB,  Just off, on left hand side, the LA to San Javier Road (Avenida de Pinatar).

Mariano is very good mechanic, with reasonable English. He delivers very good value for money. I have used him for 5 years

You should be clear on what you want: ITV stations just do that - test cars - unlike in the UK. If your car is up to date with all servicing you can simply get an appointment and take it along yourself. If you are unsure then take it to a garage for a pre-ITV check, then either you or them can go for the ITV test. It is simple enough, and I have always taken our cars myself rather than pay someone.
