Parking near SVQ?

[rafiki]

Is there anywhere near Seville airport to park long-ish term? We visit every 2-3 weeks for a few days so a car of our own might make sense if we could park it cheaply near the airport.

Seville airport is really close to the city but problem is that you would need to get a taxi each time to whatever parking place you found and each way could be say 20 Euros.
I see on the AENA site that parking at the airport itself costs €12 per day for first 4 days then €9.60 however if you have lost your Parking Ticket then you pay €60. So for parking for 3 weeks that could be €20 per week ?
But am sure that there must be some off airport parking where maybe you can get a lift to the airport included. Unfortunately the airport bus first stop is outside Santa Justa station. Maybe there is some long term parking near Santa Justa?
