sehr lecker

Ich habe meinen weissen VW Polo zur Autoreinigung gebracht und bin rundum begeistert! Der Vorher-Nachher-Effekt war wirklich beeindruckend! Der Preis ist absolut fair, vor allem in Kombination mit ihrem Abo-Modell, durch das ich langfristig sogar noch spare. Besonders hervorheben möchte ich den schnellen und effizienten Service sowie die angenehme Kommunikation. Den Termin haben wir ganz einfach über Whatsapp ausgemacht. Die Geschäftsführer sind super sympathisch und man fühlt sich sofort gut aufgehoben. Der Hol- & Bringservice war für mich noch das i-Tüpfelchen des Angebots - sehr praktisch und zuverlässig! Klare Empfehlung! Danke!
