Conscious Waiver of the Used Car Guarantee

Hi together, I collect today a Mazda 2 from 2005 with 107tkm on the clock from the dealer. The purchase price already includes the GGG used car warranty, which is in my view for the popo – I have a very important question about this, I have found feedback about the search about GGG, but nothing about my question. The facts and differences between guarantee and warranty are known to me I think the question could also be quite interesting for other users. n to the GGG guarantee: – within 5 days after handover a review in a contract workshop (I wanted to make myself, at a purchase price of 2700 and the old I do not necessarily see a car to maintain and keep waiting in a contract workshop) – with the mileage only 40% refund on the parts, 100% on the wages – accessories and attachments which are not approved by the manufacturer, let the warranty lose (PKW has tinted disks, converted wheel ioblende for a DIN1 radio and a sports exhaust and therefore I suspect that the warranty will not apply anyway) My questions are: – If I should take the warranty, do I have to use it first in the event of damage? Or can I go directly to the dealer and claim the liability for defects of property (6 months after the purchase he would have to repair the damage completely at his expense, the guarantee again takes over only a part of the costs) – I think about f to waive the guarantee and thereby possibly still 100-200 € from price (since the guarantee in my view will not take hold anyway and if the box lasts the first 6 months, it will probably continue to drive afterwards) In principle the guarantee secures more the dealer than me, since most customers will run any damages over the guarantee instead of going over the guarantee. I consider today at the handover to refuse the conclusion of the guarantee. Or mu ss I take them with me when the dealer listed them in the ad? What do you think? GGG only reaps negative feedback on the net. VG Jakub
