Euro 4 Diesel or yet a Tesla?

My good Mercedes E280 has not been in our possession for a long time, I always miss it more and more every day. As a replacement a Mercedes should come back here again, this time as E320 CDI with the good six-cylinder diesel engine, the probably best series, the W211. My partner in life said last time that you should go with the time and take more care of the environment, which I rather return to then. We have now looked at a Tesla model S with just under 295,000 kilometres. For a proud 30,000 euros. I almost lost my spit. A very good W211 with a few kilometers of the last years of construction as a fuel-efficient diesel with DPF costs around 10,000 euros. It is well known that the entry bans with Euro 4/5/6 are not controlled, so it is not necessary for a D what would you do? W211 or Model S with several hundred thousand kilometers? Greetings from Hans
