yes i want use schema.org.
i have tried to do this for each car:
<script type="application/ld+json">
{
"#context":"http://schema.org",
"#type":"Car",
"name": "Alfa Romeo Giulietta 1.6 JTDm",
"model": "Giulietta",
"brand":"alfa romeo",
"fuelType":"Diesel",
"vehicleEngine":"Diesel - 4 cilindri in linea - Cilindrata: 1598 cm3 - 4 Valvole per cilindro - Sovralimentato - Potenza max: 88 kw (120CV) a 4.000 giri/min - Coppia max 32,6 kgm (320,0 Nm) a 1.750 giri/min - Euro 6 (715/2007 - 692/2008) - Potenza Fiscale 17 CV",
"description" : "Alfa Romeo Giulietta 1.6 JTDm - 2 120 CV Distinctive (05/2015)",
"image":"assets/img/annunci/alfa-romeo-giulietta-distinctive.jpg",
"offers":{
"#type": "Offer",
"priceCurrency": "EUR",
"price": "20.850"
}
}
</script>
<script type="application/ld+json">
{
"#context":"http://schema.org",
"#type":"Car",
"name": "FIAT Nuova Panda ",
"model": "new panda",
"brand":"fiat",
"fuelType":"Benzina",
"vehicleEngine":"Benzina - 4 cilindri in linea - Cilindrata: 1242 cm3 - 2 Valvole per cilindro - Potenza max: 51 kw (69CV) a 5.500 giri/min - Coppia max 20,4 kgm (102,0 Nm) a 3.000 giri/min - Euro 6 (715/2007 - 692/2008) Potenza Fiscale 14 CV",
"description" : "FIAT Nuova Panda 1.2 Lounge (07/2014)",
"image":"assets/img/annunci/fiat-500-x-1.6-pop-star.jpg"
}
</script>
