To me there is a very simple rule to remember with cars - to you (the punter) most cars half in value every three years, note this basic rule also applies used. Some do better, lots do worse, but all cost loads£££££££££.
Lease vs buy - complicated depends on lots of factors, how long you keep, the deal you can get, the cost (or not) of finance, etc.
Each to his own. Cars are very personal, often not very rational things. Most important, get what you really want and enjoy!!!!!
