What do you mean "become like the 8 series"? Collectible? The 8 series cars are not really highly prized based on transaction prices. Ridiculously overcomplicated and obsolete? Pick any modern BMW really. So expensive to repair that it is not worth running? See previous answer.
I think I know what you're getting at but you used a stupid example. Regardless, the 1M coupe is the answer to your question.
