Johansen,
I don't manage a lot of information regarding SEL but here's a link that may be helpful (it's in spanish and I don't own any share in that cie).

Their e-mail is:

They don't operate C-172 but they list the following prices:
Piper Tomahawk PA-38 CLP$46.000 (~GBP$42)/hour
Piper Cherokee 140 PA-28 $50.000 (~GBP$45)/hour
Piper Arrow PA-28R $62.000 (~GBP$56)/hour
All their aircrafts are GPS equipped. Their prices include fuel cost but do not include additional operating costs (i.e. landing fees, etc.)
Let me know if you need more info.
Cheers
