Up to last month I owned a Cupra R and then traded it in for the Fr Tdi and i'm the new oldest at aged 46
, so I would say that you are never too old to have fun cars. And I hardly consider myself as old at 46 anyway.
Why should you start to think of yourself as being in the realm of 'old man cars'. life is for living and if driving smart looking motors gives you a buzz then so be it.
Would rather be accused of having a mid life crisis driving a good looking car than making the trek to the office everyday in a sterile looking base model.
