If you are ok with slightly higher repair costs. The best car for 1.5Mil is probably the Peugeot 406 D8.
Looks good,drives good,good market, fuel is also very decent. Comfy,safe and has some class to it also.
You can bargain a good example under 16. Find a honest technician and you will be good to go. Please find a good car with all repairs done,or you will hate everything about Peugeot.
Or if you can go for 2.5Mil, you can get a nice D9 406 with sunroof,leather,cruise control, electric,heated seats yada yada. Can be sold in a week. Really good car.
