Tell YES Roadster!

Hello, I’ve been a fan of the YES! Roadster for a long time now and I’m concerned with a possible second-hand purchase of such an exotic on the first series. The 1.8T, which was originally installed, just tells me much more than the 3.2L of the newer years of construction. I’d like to know if there might be people with YES! Roadster experience here in the forum? I’m particularly interested in how it is generally ordered with regard to processing quality, maintenance and spare parts supply of the YES!? The Audi technology used in the engine and transmission system should be less problematic than maintenance. Only what about the many own-developed parts? Especially after the insolvency of the manufacturer Funke & Will AG, I have my concerns here. Even if the production of the YES! is to be resumed by the Yes Beteiligungs- und Possessiongesellschaft mbH, founded by Marco Kunz from Edermünde. But even then it is uncertain, with this takeover of the YES! Roadster permanently secured I am therefore grateful for any information. Also gladly by PN. Thank you very much, Martin
