Dodge Challenger

Hello fellow forists & experts, I’ve been a silent reader in your great forum for a long time and have signed up now because it’s getting serious for me. I need (will) a Dodge Challenger. Simply because I like it. Either a new car – then my budget (max. 40,000) is enough for a V6. Or a used V8. Or just a used cheaper SXT. Now to my problem: Unfortunately, I’m not so fit in the matter that I can rule out using the used car. I have been checking the offers at mobile.de for months, but which dealer (somehow it is only a handful and always the same) is to be trusted? Do you have a tip for me, I am grateful for every hint. I also came across www.diepruefer.de. For 150 € the used ones check through. Does that tell you what? Thanks in advance and nice greetings Chris
