So I purchased my F50 from a very well known London specialist dealer in 2015. It was sold as having full Classiche. And I have the authentic book to prove it, dated September 2014. The car came with a magnificent Tubi exhaust system. The today she is in excellent health, and is pampered with considerable love. She's a keeper. However, last week (yes, my bad) I noticed for the first time in my F50 Classiche book, a photograph of the engine showed it having its oem exhaust system. Strange. The advertisement never mentioned the exhaust system, only that the car was Classiche (in fairness the ad comprised a shot of the engine in the showroom with Tubis). This week I contacted the dealer. His explanation was that the Classiche was conducted at his premises/workshop (he is an authorised Ferrari workshop but not a sales agent) in late 2013/early 2014. The car had not been sold to him, he merely arranged its Classiche for its then owner. It wasn't until September 2014 that the authorised paperwork/Classiche book was issued. The dealer told me by this time the previous owner had switched the exhausts (complete system). He said he had/has no knowledge of when the exhausts were switched, or what happened to the oem system. He said the work was not done by him. The car was sold to me by the dealer in Q1 2015. The problem is technically the car without its oem exhaust is NOT Classiche. I understand Ferrari changed its policy recently and requires annual checks, I guess to correctly keep track on any changes etc. The problem is Ferrari is not supplying any oem exhausts,and approximately 70% of F50s in the world have Tubis. I'm also told oem exhausts are impossible to find. I'm told Tubis are much better than the oem systems but that doesn't change the fact; no oem exhaust, no Classiche. The dealer says many of the oem exhausts were scrapped. I was a novice, and though I didn't know the importance of the oem exhaust at the time, the advertisement stated the car was Classiche, which according to the rules it wasn't at the time of purchase. But hey, my bad, ''Buyer Beware'', clearly even with reputable dealers. More to the point, if you're reading this Ferrari, may I make two suggestions before many proud F50 owners wake up to the same issue. Please either begin supplying oem exhaust systems or slightly more generous for us poor owners, allow cars which were originally Classiche but where exhaust systems have been ''lost'' to previous owners, keep their Classiche status, perhaps with a side note pointing out the change? PS: If you have a complete oem Euro spec exhaust in your storage cupboard, well done (I'm jealous). If you're the previous owner of my car and have kept it for a coffee table, please sell it back to me (the dealer said he's reaching out to the owner but I'm not holding my breath).
